Crystal Meth is better (at appropriate dosages and purity levels), as there are less side effects. There's a prescription version (Desoxyn), but it's not commonly prescribed due to it still being extremely addictive (as is Adderall, of course, but maybe not as much).<p>It's better if you can find a combination of vitamins, minerals, and supplements to help with ADHD-related issues, then add Nuvigil/Modafinil/Adrafinil and/or SEMAX into the mix.
