hii.. i use to smoke pot, but i quit about a year ago. so i can answer your questions

1.)usually just smoking, but some people make it into tea. or mix it in food if they want to be slick.2.)a persons memory is a little slow. slow reaction time. tiredness. a big boost in humor.(for some people, it can make your heart race really fast. the last few times i smoked, i started getting sick, so i quit. my heart would beat wayyy too fast.)3.)pot actually doesnt have long term effects, as some people think. only short term, which is why pot isnt as bad as people think. short term you can appear a little"dumb"sometimes. but it fades, as you stop using.4.)pot is the safest narcotic. pot is an herb. it is all natural. it is also a pain killer. it gets rid of headaches better and faster than asprin! it doesnt kill. its safer than alcohol even when youre driving.5.)people say pot isnt addictive. its really not. there is no withdrawls physically from quitting. you may want to cause it is routine for you, but definitely not addictive. i stopped easily.6.)you can get pot anywhere. on the streets mostly, but dealers have unlimited connections everywhere. if one dealer doesnt have it, his/her friend does.7.)UA's.. but people have ways of getting it out of their system before testing. like cranberry juice, pickle juice, and pills made to clean your system.8.)the commercials you see on tv are hillarious! its not like that. true, you are lazier, but pot makes you easy going. it makes you feel happy. you get along with people easily. but it makes you paranoid at times. if someone you love doesnt want you to do pot, it will effect your relationship, because you can tell when someone is smoking, based on their reaction time, and sense of humor. also the pink eyes.9.)a teenager is going to smoke pot if they want to whether someone tells them they can or not. EVEN if they have to get UA's. its something they have to realize isnt good for them on their own. but if you teach kids early enough, they will listen.10.) where im from, a dime is 10$ a dub is $20, an ounce is 100$. but thats only if its shwagg (AKA commerical weed) if its better quality, like nugs, its sometimes triple the cost of shwagg.11.)it can make you feel numb. mostly relaxed and happy. or paranoid.i hope this helps. if your boyfriend smoking pot is effecting how you feel, you should tell him. theres no need for you to be hurt, or feel uncomfortable. keep in mind though, unless his pot smoking is super bad, its not all that bad. a lot of celebs smoke it too. and if they give it to people with cancer, it cant be harmful.good luck!
