Sci will go ahead and put it out there: she hates smoking (I mean tobacco). It’s gross. It smells. You NEVER get that freakin’ smell out of your hair. And your teeth get all nasty. Not to mention to horrendous side effects, things like cancer and cardiovascular problems and death…yeah, those are bad, too.
So anyway, I think we all know smoking is bad for you. Addictive, cancer-causing, the addictive part is particularly bad, nicotine has an extremely high number of reinforcers obtained per drug session (you can only take one line of cocaine at a time, really, but a cigarette has you occupied, puffing away for a good few minutes). But now men have ANOTHER reason not to smoke: your little swimmers don’t like it.
