In California,(probably not where you're at, sorry.. but it's all I know about), you just buy some from a dispensary if you're 21+ with proof. As with some other states, if you're American. As someone who's been NOT 21 for.. forever, so far lol... I end up finding my way to some just cause I'm a devout pothead.
I love weed. I love everything about it, but for me, it's not just BEING high. It's the ritual, it's the whole activity in itself. I can do it with someone or without, and enjoy it either way.
Grinding, packing/rolling, and lighting it and just FEELING everything is amazing. Even cleaning my glass became an enjoyable part in my routine. Music is fun, during, you really concentrate on all the individual sounds and noises, everything, visually, is really bright and enhanced .. and ya just feel so damn good. Time is a little off when you're high, you may feel like you're moving faster or slower than the rest of the world. It's not scary, but if you feel like it is, just remember it's the flower and it'll wear off in a couple of hours, and you can sleep it off if needed.
If you've never smoked it, don't ruin it for yourself and smoke yourself fuckin stupid. It'll take away the part of actually enjoying the weed. Start with a hit or two and just chill out for a second. Honestly, I got to the point here for a few years where I was smoking like a chimney. Allllll day, everyday. Bongload after next; repeat. I went through a LOT of herb. Don't do that. It makes you appreciate it less.
I hope you have fun, man, I wish I could be there for everyone's first experience haha
