Crack is very powerful. Stopping once started would be impossible for anyone I think. That's not an indicator if an issue like it is for drinking. Crack literally makes you crave the next hit after hit. It's unrelenting until you either run out of money, time, access, or life.
I agree only we know if we are addicts. But for me labels are not as important any longer as the effects.
I suggest you do get assistance. Not for the physical as this is not a drug that needs it but for the harsh mental toll it can take. The distortion of what's real and what's a level of excitement or energy that is acceptable.
Crack simply makes regular living seem unbearable.
Either go to NA or AA if no NA is around. I use AVRt but for crack I think being around people is needed. It's different than just saying I will not do it again. It is th most influential drug I have ever used. Right up there with the opiates.
