As long as you dont vandalise or piss people off, then it should be fine. When I went on holiday to Thailand a few years back I sometimes stayed round the pool where my cousins house was (we stayed with him in a private estate with a communal pool) and there were Thais living there aswell. Weed was plentiful, and joints were often passed around the pool. Best place Ive ever been, very friendly people (be wary of the ladyboys though, if you can actually tell the difference!).
