I experienced euphoria for a month or so when I first started treatment, but now it feels similar to a morning cup of coffee.
I took it again after college and can say that yes if you take a high enough dose it will make you slightly euphoric but I think it's different than the high of recreational drugs. If your mood is too heightened when you take it then probably you should cut back on your dosage.
What did give me euphoria and hypo-manic behaviors was Nuvigil at 250 mg after having been off it for 2 weeks. That was an inexperienced mistake on my part, but it was really fun.
I also have no idea why anyone would want to abuse something like Adderall. The levoamphetamine targets the bodies nervous system rather than the brain. On very low therapeutic doses it cause all kinds of peripheral physicals problems for me.
It is also good to keep in mind ADD/ADHD meds have one of the highest success rates in the pharmacological field of psychiatrics care. It's one of psychiatrics success stories and there is a mountain of evidence that supports it. It is sad that it is still stigmatized as just wanting to get high. I avoided treatment for years due to that. Not accepting the proven track record of stimulant based treatment for ADD/ADHD is doing a lot of harm to a lot of people. Is it over diagnosed sure, but that does not negate that it does work for people who suffer focus disorders.
