when you take a hit make sure you suck in just your your takeing a big breath, you will probably cough because its your first time, and once you feel your lungs are almost full open your mouth and breath in...almost like you just came up frm underwater is what i can compare it to, which pushes any smoke in your throat and mouth into your lungs...you should be able to open your mouth witout smoke coming out...you only need to hold the smoke in for about 3 seconds for all the thc to be absorbed...to cover up the scent, if your smokeing outside i think it helps to stand upwind than the rest of the people your with so the smoke doesnt blow on you, if your doing it inside then blow it out a window...and put some colgne/perfume on after, not so much that its obvious your covering something...axe is a dead giveaway
