We know cigerettes cause premature wrinkles. Does weed do the same? All the chemicals in the smoke such as carbon monoxide constrict your blood vessels and starve skin cells of oxygen. Since people usually dont consume as much weed as cig smokers consume tobacco, pound for pound, would that mean that weed smokers dont have to worry about it as much? Weed smoke seems to have way more tar and irritants so I'm wondering if that would mean it would have a stronger effect on skin aging. Since weed smoke is harsher on your throat and lungs does that mean the smoke is more harmful? I assume that cooking weed or vaporizing would eliminate the effect it has on aging. How much would would you have to smoke for this to even be an issue? I guess looking older than I have to is a big deal to me.
