2Firsts Analysis: 69.8% of North American Cannabis Vapes Lack Clear Ingredient Labeling, Raising Compliance and Safety Concerns
In August 2025, the Journal of Studies on Alcohol and Drugs published a study analyzing the packaging of Delta-8 THC products in North America. 2Firsts focused on the cannabis vape segment, which accounts for 37.9% of the sample, often with high concentrations—yet 69.8% lacked clear potency information, and only 11.7% carried health warnings on the main display panel.

Key Findings from the Report:

  • Cannabis vapes made up 37.9% of the sample, including cartridges, disposables, and vape oils.
  • Nearly 70% lacked calculable potency information; only 17% clearly labeled mg/mL concentration.
  • Health warnings on the main display panel were rare (11.7%), with most warnings placed only on side or back panels.
  • Common marketing tactics included the use of “hemp” wording, legality cues, cannabis symbols, cartoon imagery, and candy-style packaging.

 


 

Detailed Breakdown:


Among the 53 cannabis vape products surveyed:

  • Cartridges: 22.1%
  • Disposables: 12.9%
  • Vape oils: 1.4%
  • Unspecified subtypes: 1.4%

 

Labeling Issues:

  • 69.8% (37/53) could not have potency calculated—labels listed only milligrams, net weight/volume, or unclear units (e.g., “Delta 8 • One Gram” without specifying whether “one gram” referred to net weight or cannabinoid content).
  • Only 20.8% (11/53) could be expressed as percentage concentration.
  • Only 17.0% (9/53) listed mg/mL concentration:
  1. Vape oils: 16.7–200 mg/mL (lower range)
  2. Cartridges & disposables: 653–950 mg/mL (higher range)

 

Health & Safety Warnings:

  • Very low main-panel coverage (11.7%) with most products only showing “Keep out of reach of children” or pregnancy risk warnings on side/back panels.
  • Some products included lab test QR codes or third-party testing statements.

 

Marketing Approaches:

  • Legality cues such as “<0.3% Delta-9 THC” or references to the 2018 Farm Bill.
  • Cannabis cultural symbols (leaf icons, “420” references).
  • Youth-appealing designs, including bright colors, cartoon imagery, and candy brand mimicry.

 

Research Team’s Warning:
Given the current regulatory environment, the lack of transparency in ingredient labeling, combined with high-potency products and youth-targeted packaging, could heighten misuse potential and public health risks. The study recommends:

  • Standardizing potency labeling in both mg/mL and percentage.
  • Increasing the proportion of health warnings on main display panels.
  • Restricting high-potency and youth-appealing packaging designs.
