This is a great idea Pothead because as many are starting to learn you can promote this attention getting item nearly anywhere and bring people in with your reference code. That's going to be a lot more btc than the item itself.

Like mouthwash , rinse till ur mouth is foamy then spit it out . I would recommend having it 20 mins before ur test just due to the fact there's alcohol and u could be done for that.
