To be honest, I never thought I'd say it but I wish they would regulate it. In my opinion the quality of tourists declined right around the time they made weed legal to purchase at every street stall in Bangkok. Ive smoked weed since I was 14 years old (I'm 50 now) but the types I see here getting stoned and about are amongst some of the lowest caste of the drug user society.
I remember going to raves in the 90s and every once n a while you'd stumble upon groups of drug users and you'd notice that something about a particular group was more desperate or dire than just your happy go lucky weed smokers. I see a lot of that here lately.
