Yet for me a few months of pot gave me a stutter for two years, and I'm pretty sure killed my motivation in my final school year. I eventually got my act together and got an engineering degree, but I'd definitely recommend against pot use.
As would I. I missed my late teens and early twenties while sitting in a haze of pot smoke, and while I did have some interesting experiences, the time would have been far better spent learning to deal with life in healthier ways. Ten years on, and I'm still dealing with the aftermath of those poor decisions.
Every time I ever got high on weed I felt lingering effects for about three days. I've never experienced this with anything else. It always seemed to me that people who smoke weed a couple times a week or more often might be slightly under the influence almost continuously and not even realize it.
