Drug, Set and SettingDrug, Set and Setting

• DRUG

– Is defined not only by the pharmacological makeup of the particular substance, but also any substance that the drug is cut with, the potency of the drug, and the method with which the drug is taken.

– Example of harm related to drug:• Injecting heroin puts one at greater risk for overdose than snorting

heroin.

Drug, Set and SettingDrug, Set and SettingSET (SELF)

◦What the individual brings to the drug experience. This includes the individual’s psychological approach to drug taking -- What is the expectation of the person taking the drug?

◦What motivates me to take this drug? For recreation? For medication? For escape?

◦ The same drug may act differently in different people.

◦ Example of harm related to set: A person who is anxious may be more likely to have a "bad trip" or

paranoid reaction if using LSD (Acid), a hallucinogenic drug.

Drug, Set and SettingDrug, Set and Setting

• SETTING:

– The environment in which the drug is taken (e.g., person’s home, bathroom in a club, an abandoned building). Setting also refers to the culture within which the drug use takes place and the messages, values, and expectations that shape the meaning of drug use within society, different communities, and subcultures.

– Example of harm related to setting:• A person who uses MDMA (Ecstasy) at a Rave with little

ventilation or available water may suffer heat exhaustion.

Drivers of HIVDrivers of HIV• The HIV Prevention Planning Council has developed a definition

and criteria for identifying Drivers of HIV in San Francisco.• A “Driver” is defined as “underlying condition that is directly

linked to a large number of new HIV infections in San Francisco.”

• Criteria for determining a Driver of HIV in SF:» Prevalence of 10% or greater. A driver has at least 10%

prevalence among one of the high-risk BRPs where the bulk of new infections occur (MSM, IDU, TFSM).

» Two-fold increase in risk. A driver is an independent factor for HIV, making a person in a high-risk BRP at least twice as likely to contract HIV compared to someone who is not affected by the driver.

Drivers of HIVDrivers of HIV After a thorough review of the literature the

following factors were identified to be driving new HIV infections in SF:
