I can just barely touch with the tip of my pinky and the tip of my thumb if my hand is splayed out - but no way with the index finger and thumb.
you know what it waaay easier? the index finger of one hand, and the index finger of another. then I can touch all day. and I do.
not as far as i know. perhaps for medicinal reasons, but the shit can still get you busted. Mind you its really low on the police's scale of concerns. they just tell you to throw it away... but they'll still do something if they see you with it
