diet spliff 

The 'healthiest' type of marijuana joint. Herbal tobacco is used instead of regular cigarette or rolling tobacco, and the skin is rolled backroll style meaning less paper is inhaled.

Diet spliffs are also a good way of fooling yourself into believing that you're cutting down.

"I know smoking weed is bad, but it's ok because I only roll diet spliffs."
