Neutral Cue-induced Craving
For the neutral cue condition, the participant will be seated in front of a 16-inch monitor and instructed to sit upright to view 20 pictures of water bottles via E-Prime software (Psychology Software Tools Inc., PA), presented for five seconds each in randomized order. The images will include pictures of a water bottle alone, water being poured from a bottle to a glass, and an individual drinking from a bottle of water. Next, participants will watch as research staff open a bottle of water, pour it into a glass, and place it on a table in front of the participant. Participants will also be asked to look at a water bottle, hold it, sniff it, and take a drink of water.
Visual Opioid Cue-induced Craving
For the visual opioid cue-induced craving condition, the participant will again be seated in front of a 16-inch monitor and instructed to sit upright to view 20 pictures of opioid-related imagery, presented for five seconds each in a randomized order. The opioid-related imagery will be customized for heroin or prescription opioids based upon the participant's primary opioid of choice. The images will include pills and white powder, stages of drug taking preparation (e.g., holding spoon over flame, pills being crushed).
Visual and Tactile Opioid Cue-induced Craving
For the visual and tactile opioid cue condition, procedures will differ depending on the participants' most preferred route of administration. . Intranasal users will be instructed to watch as research staff opens a wallet, removes a $1 bill, removes a packet of powder mimicking heroin/crushed pills, open the packet, and roll the dollar bill. The participant will then be given the packet and the dollar bill to hold for approximately 30 seconds. Intravenous users will be instructed to watch the research nurse open the packet of fake heroin, pour its contents into a spoon, added a few drops of water to the spoon, hold an open flame from a lighter under the spoon, add cotton to the spoon, and draw the fluid into a syringe.
