Conditioned place preferences for virtual reality cannabis cues

Area of Science:

• Psychology
• Neuroscience
• Behavioral Science

Background:

• Conditioned place preference (CPP) is a behavioral paradigm used to study the rewarding effects of stimuli.
• Virtual reality (VR) offers a controlled environment to investigate drug-associated cues and their effects.
• Understanding factors modulating CPP for cannabis cues is crucial for addiction research.

Purpose of the Study:

• To investigate if undergraduates with varying cannabis use levels exhibit CPP for a VR room associated with virtual cannabis stimuli.
• To examine the influence of recent vs. nonrecent cannabis use on CPP.
• To explore sex differences in CPP and cannabis cravings in response to cannabis-associated VR contexts.

Main Methods:

• 221 undergraduates (123 males, 98 females) participated.
• A VR environment was used, pairing one room with virtual cannabis stimuli and another as a neutral control.
• Participants' time spent in rooms, subjective enjoyment, and explicit preferences were measured to assess CPP.

Main Results:

• Overall, participants did not show a significant implicit or explicit CPP for the cannabis-associated VR room.
• Undergraduates with recent cannabis use (n=41) demonstrated a significant implicit CPP.
• Females with cannabis use showed a significant explicit CPP and greater cravings compared to males.

Conclusions:

• Recent cannabis use, not overall use, appears to modulate implicit CPP for cannabis-associated VR contexts.
• Sex differences exist, with females exhibiting greater explicit CPP and cravings.
• Further research is needed on acute intoxication, sex, and cravings in modulating CPP for cannabis contexts.
