I don't think it would be dangerous to use any of the lighters you mentioned, but smoking out of a can is a very bad idea.

Aluminum + smoke = brain damage
Sweet_Leaf_91 Reviewed by Sweet_Leaf_91 on . Lighters... I have a problem...i think. I have some weed and my bro and I want to smoke it tonight. however, I'm guessing my friends stole my pipe and bic lighter and the only lighters I have are a zippo (which im not sure even works) and one of those torch lighters. I was just going to make a simple bowl out of a can, but I was wondering if it would be bad/dangerous to use one of the lighters above. And I'm thinking matches wouldn't be an excellent idea either.
