Smoking scenes

So these are a few clips i found on youtube, of people doing smoke tricks. Luckily enough, I used to be a smoker. Therefore I am quite decent at doing smoke tricks, nothings as professional as these, however sometimes I can preform an "Irish water fall", and I am very good at doing hoops. This will come in handy when we act out smoking cigarettes or smoking weed. This will make the character more realistic, and will add to the role.
