7 Advancing the prevention and treatment of chronic illnesses UCLA Department of Family Medicine A Word About Marijuana Frances Jensen and David Urion

8 Abrams D, Clin Pharm & Ther, 2012. 90:844-51. 21-day RCT of TID dronabinol, smoked marijuana, or placebo – No differences on RNA (copies/mL, counts of UDL) or counts of CD4, CD8 in 62 HIV-positive subjects (Abrams D, Ann Intern Med. 2003; 139:258-266) IQ drops in chronic smokers (Meier et al., PNAS, 2012 ) Cannabis and HIV: Hazy Conclusions

9 Alcohol and HIV In the Veterans Aging Cohort Study, compared to other types of alcohol drinkers, severe chronic alcohol drinkers started drinking at younger age, had longer duration of cigarette smoking and more cocaine use (Jacob T et al., 2013. Alc Clin Exp Res; 37: 1179-1187) In the Moore Clinic, 10.4% reported hazardous drinking, 11.6% had markers indicating liver fibrosis (Chaudrey et al. 2008. HIV Med; 10:133-142)

12 While detox sounds good, less than 2 in 100 successfully achieve drug free status (Day et al., Cochrane Review, 2005) –How are public health policy decisions made? –Emphasizes chronic, relapsing nature of addiction Newly detoxified individuals are vulnerable to relapse. Opioid substitution therapy should be the first-line treatment for opioid addiction.

13 Needle and Syringe Programs Provide sterile syringes in exchange for used syringes in order to: Reduce syringe sharing Reduce time that syringes potentially contaminated with HIV, viral hepatitis and other blood-borne pathogens are circulating in the community Provide or establish contact to other health services for PWID

14 Lowering Infectiousness in IDUs: Modeling Findings Simultaneous scale-up of NSP, VCT, OST and ART implemented when CD4 cell counts drop < 350 can reduce HIV incidence up to 63% (Degenhardt et al., 2010) In countries where HIV epidemics among IDUs are established or emerging, benefits of these combinations are amplified by structural interventions that optimize access or efficacy (Strathdee et al., 2010) Advancing the prevention and treatment of chronic illnesses UCLA Department of Family Medicine

27 Social Support Informational Support “Did he give you a bug? Here’s where to go.” “Take care of your body, get vaccinated for hep A and B.” Emotional Support “Screw your partner, not your life.” “You’re worth a new needle.” Instrumental Support “Meth brings you down, meds bring you up.” “Pack your socks with condoms and lube.” Health Belief Health Threat “Is that precum or do you have a STD drip?” “Meth can take your teeth.” Health Behaviors to Reduce Risk “Dip it, don’t stick it.” “Inject clean, an abscess is a hot mess.” Awareness of Health Risks “50% of men with Chlamydia have no symptoms.” “Using meth in public can be risky.” Social Cognition Self-regulation Skills “Weekends getting longer and longer?” “Don’t have an open sores relationship.” Self-Efficacy “Say 1 st thing your poz, like you did last time. You can do it.” “You can take your meds, even when you party.” Reback et al., (2010). Open AIDS Journal. 4: 116-122. Theory-based Text Msgs for Stimulant Use
