Is there any good news about Meth?
• Local declines:
– – – – – Monitoring the Future declines Meth crimes in Montana Employee urine tests in Montana ED admits in San Francisco Mom & Pop labs in US

• But:
– Increases in meth deaths in South FL (77 in 2003 to 115 in 2006) – 25% of gay men tested for HIV at LAGLC reported using meth in past year at least once (Rudy et al., 2007) Predictions in decline in meth use have been published since 2005.

The Social Construction of a Gay Drug: Methamphetamine Use Among Gay and Bisexual Males in Los Angeles

The Meaning of Identities

• Gay/Bisexual Identity • Methamphetamine User Identity • HIV Identity

The Meaning of Identities: Gay/Bisexual Identity
• • • •
Participants expressed the importance of sex in their lives Participants discussed the relationship between their gay identity and gay sex For many, methamphetamine use is a positive coping mechanism For others, their methamphetamine use is consistent with positive gay sex and sexuality

Gay/Bisexual Identity
“It [meth] removes all old guilt and shame and makes me feel sexy. . . . We were all brought up in an environment where gay sex was bad, wrong, and could do all kinds of horrible things to you. . . . It’s a way for gay men to have sex with some of that lifted.” Focus group participant

“Crystal has a special purpose for gay men because so much of the way we use it is based on our sexuality or the kind of sex we have.” 29 years old, Pacific Islander, HIV-

The Methamphetmaine and Sex Experience
• All participants discussed the enhancement of their sexual activities while on methamphetamine:
   

Heightened sensory experiences Disinhibiting effects Duration of sexual arousal Intensified orgasms

“I’m not sexually excited unless I’m under the influence. . . . I don’t have sex without crystal.” 29 years old, white, HIV+

The Meth / Sex Experience

“All your senses are ascending . . . suddenly awakened and not dormant. Like being born . . . it's like every pore is cumming.” 51 years old, white, HIV-

“On crystal it’s [sex] more experimental; you’re willing to try anything on crystal. 27 years old, African-American, HIV-

The Meth / Sex Experience

“When I’m on speed and I have sex, it’s just a freaky sex . . . it’s freaky, kinky, wild, just crazy fucking sex.” 17 years old, Native American, HIV-

“When I cum, my body goes off the goddamn bed . . . that is how fucking intense it is.” 48 years old, African-American, HIV+

HIV Identity

“In the 1980s when all my friends were alive it was the gang getting together for dinner, the gang doing this or that. But, they all died. I’m a long-term survivor with HIV. I’m like here and they’re not. So my weekends can be very, very lonely. And, as a result of that, my drug usage increased.” Focus Group Participants

The Impact of HIV
• The impact of HIV continues to be a salient factor directly influencing the sexual lives of gay men • At this historical moment gay identity is still linked to HIV and one’s sexual expression becomes infused with death

• Participants report using methamphetamine to:
_ _ _

dissociate from fears associated with sex cope with grief and loss alleviate physical and psychological HIV-related pain

The Impact of HIV

“I’m the one that’s sick. The methamphetamine use is insignificant compared to the other problems that I’m dealing with. If it relieves any part of that physical or mental pain, then I will do it.” 43 years old, white, HIV+

The Social Construction of a Gay Drug
• • •
Many of the effects associated with methamphetamine use complement valued aspects of gay culture Methamphetamine use is facilitated through various gay institutions such as chat rooms, personal ads, circuit parties, bars and clubs All participants used methamphetamine during their sexual activities. All participants discussed the enhancement of their sexual experiences while on methamphetamine. Sex was seen as more intense, heightened, prolonged and uninhibited. Several HIV-infected participants discussed the advantages of using methamphetamine to manage AIDS-related conditions or effects.

HIV Infected MSM Drug Users
• Project INSPIRE: HIV+ meth users engage in sex risks, but IDU not predictive of unprotected anal sex with negatives (Purcell et al., 2006)
– HIV+ IDUs have significantly more healthcare and economic disparities, lower employment, income, less gay identified, likely AIDS dx, sexual abused (Ibanez et al 2005; Semple et al., 2004)

Meth triples HIV Incidence in MSM
• MSM HIV incidence = 1.6 per 100 ppy (95% CI=1.231.95; Buchbinder et al., 2005) – Corresponds to 19.1% prevalence (95% CI=12.8% to 25.3%)

• Detuned assays of 290 MSM meth users in SF at anonymous testing sites: Incidence estimated 6.3% (95% CI=1.9-10.6) compared to 2.1% (95% CI=1.32.9) for 2701 non-drug using MSM (Buchacz et al., 2005) • MACS: HIV seroconversion increased ~3 times for MSM who use meth and poppers (Plankey et al., 2007)

Special Issues for Methamphetamine Using MSM:

Medical Consequences and HAART

Medical Complications of Methamphetamine Abuse
• Rapid heart rate, high blood pressure, rapid breathing, high body temperature, agitation • Kidney disease and strokes • Heart attacks, especially in young patients (29-45) • Meth smoking associated with acute pulmonary hypertension: inability to catch one’s breath • Impairs CD8 T-lymphocyte function
Urbina A, Jones K. Clin Infect Dis. 2004;38:890-894.

Chronic Effects of Methamphetamine Use • Psychosis, depression, violence, family and social disruptions, criminal activity[1] • Among MSM, abuse increases likelihood of infection with HIV[2] • May exacerbate neurotoxicity and other pathological processes common to HIV infection (Markowitz et al., 2005)
– May worsen the HIV epidemic and complicate treatment of HIV[3]
1. Peck JA, et al. J Addict Dis. 2005;24:115-132. 2. Shoptaw S, et al. Drug Alcohol Depend. 2005;78:125-134. 3. Urbina A, Jones K. Clin Infect Dis. 2004;38:890-894.

Methamphetamine and Protease Inhibitors
• Protease inhibitors commonly metabolized by liver enzyme, CYP3A4 – Ritonavir also induces CYP2D6 enzymes – 3- to 10-time increase in levels of MA or MDMA in patients taking ritonavir[1] – Deaths reported for HIV patients using MA and MDMA; all reports indicate ritonavircontaining regimens – SAFETY POINT: Urge patients to talk with HIV docs about their meth use
1. Urbina A, Jones K. Clin Infect Dis. 2004;38:890-894.

Methamphetamine Interferes with HAART Adherence
• Use of drugs, especially stimulant drugs, reduces HAART adherence • 3-day reported adherence rates:
– On stimulants: 51% – Off stimulants: 72%

• Main effects of meth observed on behavioral organization
Hinkin et al., 2007, AIDS & Behav 11:185–194;
Arnsten et al., 2002, J Gen Intern Med 17:377-381

Intervention Strategies

Evidence-Based Treatment Targets
• Pharmacological Targets
– Substitution (agonists, e.g., modafinil) – Relieve withdrawal symptoms (e.g., bupropion)

• Behavior Therapy Targets
– – – – Instilling of abstinence Prevention of relapse Improve mood and cognition Reduce craving

• None of these targets imply cure

Treatment Algorithm?
• What level of treatment do you recommend?
– ANS: Start where the patient is at
• Least intensive form of treatments precede more intensive treatments

• When do you recommend treatment?
– ANS: Within moments of the request

• How do you know when is enough treatment?
– ANS: You don’t

• What do you recommend for lapse? Relapse? Worsening use? Continued use?
– More of the same? Or something different?

Psychology of Meth Abuse
• Disorder of impulse control
– Cognitive and behavioral “brakes” are shot

• Key factor is ambivalence
– The unresolved tension: is it a problem or is it no problem?

• Lots of omorbidities…but which do you treat, and when? • How do you know when your patient is lying?
– Essential to use biomarkers – get a urine sample!

Cultural Factors in Interventions

• Drugs always have functional aspects that facilitate their use • These functional aspects are important to treatment process:
– Increased productivity – Weight loss – Enhance sexual functioning – Organizes aspects of culture

Methamphetamine Medications with Promise?

• Buproprion showing some efficacy for light users (Elkashef et al., 2007) • Some initial evidence for methylphenidate (Tiihonen et al., 2007) • Use of modafinil as a treatment for fatigue with HIV-positive patients in treatment (Rabkin et al., 2004)

All of these are in early efficacy trials

Methamphetamine-related Barriers to HIV Medication Adherence
• For some participants, non-adherence related to methamphetamine use was conscious and planned: _ Partying/escape/medication vacations _ Avoiding drug mixing and toxicity

• For other participants, non-adherence related to methamphetamine use was unconscious and unplanned:
_ Inability to maintain a schedule _ Sleeping through doses _ Inability to eat or drink

Methamphetamine-related Medication Nonadherence
Gerry: “When high, I didn’t take my meds, I didn’t think to. The adventure would just start and I would go with it and I wasn’t planning. I didn’t plan and I wasn’t prepared. That was part of the fun of the adventure, that it was so spontaneous and impulsive.”

Wayne: “I don't do any [meds] while using. When I do use [meth] I'd literally lie on a bed in a hotel, bathhouse, or my house, and I barely drink any liquids or eat. And that might be twenty-four hours. I have total focus on just having sex. Nothing else matters… [The meds] don't enter my mind… I don’t even shower. I couldn’t care less. If there was a way that I could pee without getting up from sitting there and masturbating, I would have invented it.”

Rich: “If I’m not on drugs, it’s pretty much habitual. I wake up and take my medicine or go to bed. I don’t even think about it. When I’m using crystal there is no going to bed and usually I take my medicine when I wake up and when I go to bed. I know that I should take it at a certain time because that’s when I normally would wake up but [on meth] I might just let that time go and go and go.”

Matthew: “I’d miss so many doses and then try to take it. You don’t keep track of time, you don't keep track of food schedules and stuff. With crystal, the schedule was blown out of the water.”
