I am disappointed that an Amsterdam pot cookie had such a mild effect on you. Take two next time and you'll definitely notice the difference. A $7 brownie from one of my local medical marijuana dispensaries would likely have you laid out on your back incapable of functioning while going on a multi-hour psychedelic odyssey into your own psyche as well as experiencing such vibrations to a degree of strength on the same order as orgasm. You might rate it an event of profoundness on the order of a birth of a child.

And if you take it frequently you also get to experience the perspective altering state of having approximately 10 less IQ points!

There are far better recreational drugs to play with. Perhaps the only advantage pot has is convenience.
