I'm currently dating this chick that smokes constantly and I never smoked before and it's not because I have been able to, it's because I'm studying to be a physician. I started dating this girl because she's hot and I decided to give it a try and I can tell you weed does impair cognitive function. It's nearly impossible to hold an intelligent conversation with her because she forgets what we're talking about half way through. Anything we do is instantly forgotten the next day. I've talked to her about this and she swears she doesn't remember the things we do or talk about. I've asked her if she suffers from short-term memory loss and she claims that she doesn't. Nonetheless It is suspicious that the first girl I date that smokes on a daily basis is slow in the situations I've mentioned
