What is psychosis defined as, and how is it any worse than the effects of excess alcohol consumption?
On 30+ years, I have never seen someone get violent from cannabis, but with alcohol, it is a regular occurrence.
Worked at a hotel when I was younger too, and you can bring me a hotel full of people high on cannabis, and the worst they ever did was buy a ton of snacks.
Alcohol, on the other hand, was responsible for noise complaints, broken televisions, furniture, sexual assault, violent assault, cops being called all the time, etc.
