I'm not talking about employment, they most likely will drug test. I'm talking about when you are in the process of getting certified. I smoked weed a couple days ago. And there is a lifeguard tryout next week which I think I will do. I plan to get certified soon, and then get a job in about 4-6 months (school schedule doesn't allow me to have a job now). I'm not a regular smoker so don't think I'm a stoner or anything. Think if it like someone who gets drunk at parties occasionally.
