According to Yahoo news, some pot smokers are taking advantage of the new "e-cigarettes" that vaporize liquid nicotine, for tobacco smokers, and using that same process for marijuana, who’s smokers must use cannabis in wax or liquid form. When someone is "vaping" in public, it's impossible to tell what substance he or she is imbibing.

Liquid marijuana does exist and is a very popular item in marijuana dispensaries, vapor pens easy to find in pot shops... and it's getting easier every day..

Sound off in the comments below - do you think marijuana should be available (where legal) in liquid form?
