Description
Lukas Eggenberger and colleagues follow, in a 2026 Swiss longitudinal cohort study, 731 young adults whose hair was tested for more than one hundred substances at ages twenty and twenty-four. Hair testing captures real drug exposure better than self-report. Patterns of change were grouped into profiles, then related to thinking tests and mental health symptoms at twenty-four.
Among those with any use, five change profiles emerged, from a large low or decreasing group to smaller groups increasing cannabis, club drugs, medical stimulants, or medical sedatives. Cannabis increasers showed weaker attention and higher anxiety, depression, and attention-deficit symptoms than non-users. The objective timeline helps prevention programs see which escalation paths carry mental health costs.
