College students who use more cannabis are less willing to share it, and less likely to use it with friends
Cannabis is often a group activity in college, but the pattern looks different among heavier users. Students who used more often shared less in a hypothetical sharing task and were less likely to use mostly with others.
A recent study published in Experimental and Clinical Psychopharmacology has found that college students who use cannabis more frequently tend to be less willing to share a hypothetical supply of the drug and less likely to use it with friends. These findings suggest that heavier cannabis use is associated with valuing the drug more and consuming it in less social settings.
The researchers hope that this pattern may eventually help identify individuals at risk of developing problematic cannabis use. The study comes as cannabis consumption among young adults in the United States has risen alongside the expansion of state-level recreational legalization. Between 2013 and 2023, the proportion of young adults aged 19 to 30 who reported using cannabis within the past month increased from 18.3 percent to 28.7 percent.
