You can say your age here. We're not here to help you steal or break the law, spend the time you spend stealing mowing lawns or doing bake sales if you really are having that much difficulty finding a job. There is
always a way of making money.
DXM is not a psychedelic, it is a dissociative, similar to PCP, Ketamine etc. Personally if you're young I don't think dissociatives are a good idea in the first place (as I mentioned in your other thread), as they're very addictive and can cause problems in the long run. If you must trip I'd say traditional psychedelics are a much healthier, safer, and more useful alternative for a young mind.
Unless you count research chemicals, which must be bought online or at headshops (though I wouldn't recommend the latter, since it's usually "party pills" without you knowing the ingredient, which can be dangerous.) - the only OTC drugs you can get with any sort of hallucinogenic effects are deliriants.
Deliriants are dangerous and also - not the least bit pleasant, you can achieve pretty much the same effects as deliriants by depriving yourself of sleep for a couple of days. The most commonly used OTC deliriant is Diphenhydramine, aka Benadryl (though not all Benadryl products contain Diphenhydramine, always check the label and make sure it's the only active ingredient) - you can check the
Big & Dandy Diphenhydramine Thread for more info, but unlike DXM it doesn't really offer any sort of high, just (usually scary) hallucinations that seem as real as day and can lead to you doing very stupid things like forgetting you took a drug and getting seriously hurt or worse.
DXM is definitely the safer option of the two, though I still wouldn't recommend it. You don't really have any other options. I'd recommend finding yourself access to traditional psychedelics if you wish to trip
Anyway, we don't allow "What should I take?" threads here at Bluelight, so..
