talking about doing drugs isnt illegal. anywhere.
you can do it to a cop, though he would have the right to search you then. but you cant be charged for talking about drug use, or allowing it. things are not crimes and people are not criminals until they are charged as such.
dont let your insecurities and scare tactics from mommy make you think otherwise. cuz there is nothing more that authorities want, then to make you feel like a criminal and think everyone around you is one. they win that way.
