Can make me horny
Oh dear god this is so true for one friend of mine. Whenever we bun he finds it necessary to point it out, it was funny the first couple of times him on the floor rolling about giggling and saying "I'm so hoooooooorrrrnyyyy" but now his constant lewd sex jokes are tiresome.
Anyway it took me about 3-6 months to truly get a grip of how to best enjoy weed and fully comprehend what it does. Everyone's different but personally I prefer to roll a massive spliff and sit outside listening to music with some friends. When I first started we all rolled loads of weak ones and as a non smoker the tobacco made me feel baaaaad. By that I mean depressed and nauseous. Although I reckon the depression was the feeling bad accentuated by the bad side of weed. Loads of people like to watch movies, I don't I find them too hard to follow, I only like to watch movies I've seen. The Big Lobawski is amazing to watch

. If you get paranoid I find a couple of beers pre smoking takes any edge of. It ends up being a really mellow sleepy version of alcohol, although it is a combination that for most people means vomiting, you do need to find the perfect balance for yourself. Also being stoned whilst really drunk makes the room spin like a mother fucker.
Personally I find that the perfect amount is just enough to make me "zone", but not too much so that when I close my eyes it feels like I'm rocking or my body's being pulled in different directions. As for the "zoning" I'm not sure if other people get this and it rarely ever happens any more (I guess I smoke too much), it was mostly when I first started that I got it. The best way to describe it is I suddenly after random periods of time, from about 5 minutes up to an hour, zoom back into reality and being sober. I realise that whatever I'm saying or doing is ridiculous or stupid, what I was in the process of doing feels like it happened yesterday, then gradually (or pretty quickly if I'm quite fucked) sink back into intoxication. About half of the time its someone mentioning how stoned they are that makes me zone. I once had some killer brownies made out of fan leaves of some homegrown, got me more fucked than anything I'd ever smoked although considering there was about 50grams of fan leaves per brownie its not surprising. I would zone every minute or so and during the process of me saying the sentence "I'm too fucked" I'd already be gone.
Strain also has an effect. I find the weaker stuff, although weaker, has a nicer high. Nicest stuff I had was a couple of weeks ago. We smoked about 2 grams between 4 people which for the quality of weed we get here is enough to be very baked (or maybe we're just crap and girly?). I didn't feel all that stoned, but I got the giggles worse than I'd ever had them before. Literally everything was serial and trippy, even if it wasn't and I laughed so much I cried. Also the ceiling on the high was really low. I didn't feel much more stoned after the 3rd spliff compared to how I did after the first one.
I hope you learn how you like to use it, I personally can't smoke it on my own, but I know people who can't smoke it with other people. To each his own.
