crack. It lasts like a one pump chump and is super fiendy. You will blow hundreds of dollars in a night smoking crack. It is equally as bad for your health and mental health long term as meth.
Best suggestion is to not smoke either though. Regular coke is fine and longer lasting. Meth has much less fiendish roas like snorting and eating. Trust me, you don't want to start obsessing over the pipe it WILL escalate your addiction and that will potentially run you down.
