Regulated cannabis from authorized pharmacies
"The intervention group is allowed to purchase regulated cannabis in authorized pharmacies. The intervention includes various offers: Participants can choose between cannabis sorts and delivery methods, and they are encouraged to shift from smoking cannabis to vaping cannabis-containing e-liquids, vaporizing cannabis blossoms or using oral cannabis. Vaping / vaporizing electronic devices are also recommended. At the same time, pharmacists offer opportunistic smoking cessation and problematic cannabis, alcohol use and further drug use counseling that conforms to motivational interviewing principles.~Study participants can choose between different cannabis-containing products such as dried cannabis flowers, cannabis concentrates (colloquially called hashish or hash), e-liquids and oral cannabis. Besides the cannabis products, participants can buy vaping or vaporizing electronic devices at the pharmacy (they are not considered as study products)."
Cannabis from the illicit market
The control group receives no intervention and is expected to continue purchasing cannabis from the illicit market.
