AM I ADDICTED TO DRUGS?

okkkkkkk when im 15 and i started smoking weed when i was about 13 and did it couple times a week and every week and over summer almost everyday. now that im 15 i dont like smoking anymore cuz its just not as fun anymore like ill do it whenever people have it n **** but ive been doing alot of pills lately and stuff like (blues,oc 80s,xanax,valiums etc.) and like i do them about 1-2 times a week and almost every weekend like i dont feel like i ever need anything but i just dont want to be like addicted and im only writing this cuz ive been stealing oxy 80mg and blues(roxy or oxy 30mg) if you dont know what they are from my friends dad bout every 2 weeks and i know not to ever do like herion or coke or meth or crack and that stupid stuff but just the feelings of all these pills are sooo amazing and like all my friends do it even though i started them off doing them so i kinda feel like a and i geuss im only wrinting this cuz i just snorted 2 60mg of morphine sulfate and like i dont even know why i do them? just i guess cuz their fun and **** and i smoke cigs a lil bit but my parents found out i smoked so i mostly stopped cigs but weed sometimes mostly when im on roxys or oc 80s and my parents are starting to think im drinking or smoking (weed) cuz they say ive been acting different and stufff but its the pills but like im 15 so they wouldnt think id be doing pills? idk i just feel bad and wanna stop but at the same time i dont cuz its really fun and just like social and **** and idk i like to do em hahah but the only time i ever felt like i needed anything was when i was doing 2-3 roxy 30mg a do for about a 2 weeks but then i got over it and stopped doing roxys for like a week and started xanax,valuims and now ive been doing morphine a lot and am doing roxys about once a week and idk i dont think im addicted though?
