Do you think i have a drug problem?

A little over a year ago i had my first experience with weed. Then i started doing that more and more until i was smoking it everyday. Then during the summer i did DXM twice. Then i tried the big bad...crystal meth. Shortly after i tried ecstasy and then cocaine. ive tried meth at least 10 times but its been 3 months since doing. i used to snort 3 lines before school but then i stopped because i ran out and didn't have the connection or money. ive always tried xanax bars and ambien. Do i need to go to rehab? i still smoke weed though and cigarettes...
