Marijuana is less addictive than alcohol or tobacco.

Sure it is. How long have you been smoking it?

[Know your rights]

Sure it is.

Of all those who have used marijuana, 9% have at some point become dependent; the corresponding figures for alcohol and tobacco are 15% and 33%.

How long have you been smoking it?

I haven't used it in well over ten years. How long have you been using alcohol and/or tobacco?
