Clinicians Report Increased Teen Cannabis Use, Higher Potency Products, and More Hyperemesis After Legalization

QualitativePreliminary evidence
The takeaway

Thirty-two clinicians across multiple specialties described post-legalization increases in adolescent cannabis use, uptake of high-potency products, cannabinoid hyperemesis syndrome, and cannabis-related psychosis, alongside decreased perceived harms and more permissive parenting.

Pediatricians and adolescent health specialists; cannabis policy makers.

Clinicians from all 4 specialties reported increased adolescent cannabis use and high-potency product adoption

What the researchers found

Clinicians reported post-RCL increases in adolescent cannabis use, non-combustible modes and high-potency products, younger first use ages, and self-medication. They described shifts in social norms, appealing marketing, easier access, fewer perceived harms, greater parental permissiveness, more cannabinoid hyperemesis syndrome, increased psychosis, and decreased court-mandated treatment.

Why it matters

Clinicians across specialties are observing a consistent pattern of adolescent cannabis-related changes post-legalization that quantitative studies have been slow to capture. Their perspectives on high-potency products, psychosis, and parental permissiveness provide early clinical signals that deserve population-level investigation.

The numbers in context

32 clinicians interviewed (56.3% female, mean age 45.9 years, 65.3% non-Hispanic White). Four specialties represented: Addiction Medicine (n=13), Psychiatry (n=7), Pediatrics (n=5), Emergency (n=7). Interviews conducted September 6 to December 21, 2022.

How the study worked

Semi-structured qualitative interviews with 32 clinicians from Addiction Medicine (n=13), Psychiatry/Mental Health (n=7), Pediatrics (n=5), and Emergency Department (n=7) in Kaiser Permanente from September-December 2022. Thematic analysis of transcribed interviews.

What this study cannot tell us

Clinician perspectives are subjective and may reflect selection bias (clinicians who see the most severe cases). The sample is from one healthcare organization in California. Without quantitative data, it is impossible to determine the actual magnitude of the changes described.

How to read the evidence

Preliminary: systematic qualitative study across multiple clinical specialties, but relies on clinician perceptions without quantitative confirmation.

When this study was published

2024 study using 2022 interview data.

The bigger picture

The combination of decreased court-mandated treatment and increased permissive parenting suggests that the formal and informal systems that previously motivated adolescent cannabis treatment are weakening post-legalization. This creates a gap where problematic use may go unaddressed longer.

Questions still open

  • Do quantitative data confirm the increases in CHS and psychosis that clinicians report? Has the elimination of court-mandated treatment measurably decreased adolescent treatment engagement?

Common questions

What specific changes did clinicians see in teens?
Clinicians described teens using cannabis at younger ages, gravitating toward high-potency products like concentrates and vape pens, and increasingly viewing cannabis as benign. They also noted more teens presenting with cannabinoid hyperemesis syndrome and cannabis-related psychosis.
How did legalization affect parents?
Clinicians reported that many parents increased their own cannabis use post-legalization and became more permissive about their children's use. Some parents were described as not viewing adolescent cannabis use as problematic, making clinical conversations more challenging.
