phrozenI was always under the impression that the appearance symptoms caused by meth -scabs, bad teeth, gaunt appearance, etc - are caused by the lifestyle, and not actually the drug itself.
This is absolutely true. People tend to not eat and not brush there teeth, general neglect, lack of sleep. As far as dentation, the combination of decreased saliva production and tweekers grinding there teeth definately take a toll on one's teeth. My old dentist was in Hillcrest (the gay part o San Diego) and meth mouth was real. However, better dental hygene and saliva substitutes should help. I've seen many long term tweakers with all there natural teeth even after decades of use (this is San Diego with a long tweek legacy).
Skoat mentioned a yellow tinge from chronic use. Pasty white, ashen grey are the colors I normally see. However, I have seen more than one tweeker with a bit of jaundice. This is especially true among IV drug users that tweak and have a history of hep A or B. Chemical hepatitis is deinately a possibility with this drug as there are many different synthetic routes, adalturants, ect...
Back to topic, consumption of porn and meth go hand in hand, more than any drug I know- in males that is. My wife- although she usually isn't into male oriented straight porn would become so on tweek. For males: I've had multiple orgasims on tweek but it usually makes it hard for me to cum. Always wanted to know meth , and this is a question in which variability is inherent, how meth changes females resposiveness to straight male oriented porn, or porn in general. I know, this is a question or which there is no easy answer. In a perect world, preludin and ludes in particular would probably be the ideal drugs to enhance the experience.
However, from my cursory understanding of the industry, and from this thread, substances promoted are ED drugs or males and artifcial lubricants or females.
I saw a swedish porn film on VCR were the actors were obviously on speed- you could tell rom their weight, jawing (stereotyped behavior) and general manerisms. The girl was a red head with braces by the way.
