Isn't the substance abuse risk solved by dextroamphetamine precursors like Vyvanse? 50% vs placebo is nice but how does this compare to stimulants? BTW it is not widely known but the graal stimulant does not exists yet. Vyvanse has a unique value proposition but is only a prodrug to dextro amphetamine, in order to be optimal (for some people, results may vary) it would need to also have a levoamphetamine prodrug. I don't think such a prodrug has been discovered yet.
