MajMike Reviewed by MajMike on . Little things you do to minimize the damage... regardless of if it really works I worry a teensy bit about health concerns from smoking. So far so good, but I've been smoking for 20+ years so I won't be surprised if it catches up with me someday. Whenever I'm smoking I try to fully exhale allll the smoke out after each hit. I smoke alone 9 out of 10 times but even if Im w others I dont look like a dumbass doing it, I've got it down to where no one can tell Im being weird, lol. and I most always take a drink after each hit too, I guess I figure it washes any baddies Rating: 5
