Well yes they are slightly higher (4%) whereas alcohol is (2%), both of which are way down the list as the main causes of death in Thailand (2021). However my comment was concerning the banning of smoking cannabis in Thai schools versus drinking excessive alcohol, both being classified as drugs. Deaths due to poor driving is an entirely different cause.
