1. People who smoke weed tend to drink less alcohol, so there are obvious side benefits.
2. There is a real and more dangerous issue in Thailand with synthetic drugs (most of all Yaba, but also others such as Fentanyl, Ketamin, etc...). It's inefficient for authorities to lose time on weed. Attention must be focused on synthetic drugs, not only to fight against traffic, but also to provide rehab solutions to drug addicts (instead of just putting them in jail).
