I doubt that there are many people who have had tobacco in as wide a variety of ways as I have since most nicotine addicts find one form they like and stick with it. Accordingly, I question the ability of many people to identify various smokable items quite as well as I can. And I have never seen a clove that smelled or tasted like pot. Trust me, I’ve been around enough clove smokers (myself included) and pot smokers to know the difference!
However, a beedi is a whole other story. The unflavored ones taste a little like 420 and smell similar enough to at least raise a few eyebrows even amongst those that know better. The flavored ones… well, they generally taste like soap; the flavoring agents are horrid!
