This was a hard call
In terms of a rush
IV meth is fun but doesn't have as much of a kick as IV cocaine
Smoked crack and smoked meth is almost on par, but crack definitely has the upper hand.
Winner: Cocaine. It's just something about it that has a harder impact on it's first impression when you meet the white girl.
Duration
Now meth definitely has the upper hand when it comes to duration. Euphoric and long lasting, whereas cocaine is not that long lasting. It's great for a quick rush, but 20-30 minutes later, you're down in the dumps. Meth has euphoria and productivity, which makes meth great for long days that are ahead of ya.
Winner: cocaine is definitely great for fast paced fun and quick rush, but meth is fun in the long run in the literal sense.
Conclusion
Now this was a hard decision. As an avid opiate user, I love mixing stimulants with them. The rush of a traditional speedball( coke and heroin) is intense and powerful and I can see why the feeling is so great, but meth and heroin seems to be great when it comes to long shifts at the job. Gets rid of leg pains and back pains, along with anxiety, while the meth keeps me awake from the nod in the middle of my shift and helps me feel confident and alert.
Winner: as much as I love cocaine, I do love methamphetamine for it's long duration. Methamphetamine is what I chose for my personal preference.
