Dextroamphetamine really does it for me; I've recently gotten quite interested in them. My friend shares his Vyvanse with me and I'm trying to find some Adderal but it's really like the perfect drug for learning when used recreationally. Apparently long term memory may be impaired with heavy use but only the online encyclopedias are telling me this, I've never heard it of it myself though through first-hand friends or the internet. However, whenever you're on (and above the recommended dose; recommended and under-tolerance dosage subtly increases focus/motivation/memory but it really doesn't feel the same as when it's abused. When my tolerance to it drops, Vyvanse makes me Super-Student. I can ace tests, finish homework easy-peasy, and have a compulsive need to either write about anything (ie. this post) or do something; not doing something sometimes feels like wasted time when sober I'd be relaxing and just being patient. I really dig the slight euphoria from it but it's really the focus, increased confidence, and motivation and passion (to do yardwork, homework, research, read, anything) that takes the kill; it makes me actually care about school, about my hobbies (which this drug actually has inspired two of in a month), about current events, about anything -- even things you don't care about suddenly are, if not interesting, then at least do-able. I understand Shakespeare which sober I absolutely hate reading, I think his work is meant to be seen on stage first hand. I get obsessed with Edger Allen Poe when I have down time. When I'm ahead of the rest of my math class, I go back to old worksheets and do old problems over again so I can remember them better. And most importantly for me, I can't shut up, I'm pretty introverted and I don't like it; amps fix that, I'm positive, confident, funny, easy going, passionate, and open about things I'd otherwise never even think of sharing despite being hugely important to me.
Amps are absolutely amazing for schooling or even personal research (I've used it for both) when taken recreationally; other than that, I can't focus or even feel motivated to do work (let alone anything) on any other drug I've tried. Stimulants are really the way to go if you want to experience learning high somehow. I've considered trying Ecstasy at school and seeing how it'd affect my motivation because I've heard it's a huge boost for self-confidence and openness (which I would suspect leads to motivation) but I'm not sure of it's affects with focus, I've never heard of anybody rolling in school besides at dances (my plan for next month). With cocaine, I'm not really sure, I only know one person first-hand who's done it and he's not the sort of person who would care about school even if he took amps, you know what mean? It improves self confidence and other very extroverted things but I've not once heard of anyone using it to improve school work, despite hearing about people doing it in school. From what little I know about it, I think when people snort coke in school it's to get high and just to get high -- although you could argue an addict wouldn't be able to focus or care about much while going through withdrawals or crashes.
Weed has only helped me come up with new ideas and be a little more outgoing than normal but forgetfulness and confusion usually outweigh the positives for me at least. I don't think anyone in their right minds would try to learn something while on the big hallucinogens in an education system; personal education with hallucinogens is very hit or miss, thinking back on trips I did incredibly easy things terribly wrong like how to get money out of my wallet or deciding driving was a good idea. So to me at least strong hallucinogens may help you look at something in a totally different light but I don't think trying to teach yourself something while on a trip would get very far. However, I have heard of people really liking to read on a comedown and people who take very small doses of Acid and get mild, confidence and mood enhancement which I would consider a key aspect of a learning drug.
As for depressants, they never seem to affect education except make me happier. Alcohol is risky because it's so noticeable in a school system but the one time I was drunk at school, I had mostly sobered up by the time I had to actually sit down and learn but all that I noticed form a learning standpoint was increased confidence. Being drunk has never encouraged me to do much of anything but sing obnoxious songs anyways. Opiate painkillers I really love. I get them in school a lot and just pop them; they don't help me learn except by getting me through a tough day happily. I love them, but if anything they just encourage me to talk to my friends and enjoy myself. The improved confidence never would direct itself towards education. I've done Seroquel (Quetiapine) in school a few times and I never really liked it at all besides the kids I did it with ensuring me it was their favorite pill. It doesn't help me focus one bit, just depresses the life out of me, makes me kinda dizzy (which is kind of nice but lots of drugs do that alongside euphoria which Seroquel lacked for me at least) and makes me want to sleep but my heart feels like it's trying to pop out of my chest. Depressants just make me socially confident but I can't focus for **** when I'm on them.
IN CONCLUSION: To my knowledge and from personal experience, which please note is not very extensive and I'm new to the forum, stimulants (especially amphetamines) really are where it's at for learning something new, studying, or just school in general. They don't turn me into a different person like hallucinogens do in some respects. I still know the same things and have the same opinions, I'm just more confident to talk about it and more accepting to subjects I otherwise don't care for. Hallucinogens are good at looking at something in about as right-brained a way as it will let you, but they really aren't helpful in learning something new that you're going to need to remember in a left-brained fashion. For example, a chair isn't just a collection of atoms and energy when you trip; it can be something hugely metaphoric or spiritual with a good dose; but if you need to make a chair blueprint for shop or math class or something, you're screwed. Weed is good at this too, to a lesser level which means you'll comprehend things better, unless you're like me and pot just makes you confused alongside euphoria, different sensations, etc. The confusion is really what kills it's potential to be a learning aid. Depressants don't really help too much for learning but they can bring an introvert out of their shell really well which does help learning in some ways.
As far as learning aids, stimulants seem to be the best in making you an avid learner and good student if that's your fix. OR they could lead you to write a mini-essay about drugs as learning aids, like with me. Sorry if it's a long read, I only meant for this to be a couple paragraphs but by the second or third I kind of decided to take it in another direction. I get carried away typing things when I'm on speed; last time I wrote an essay on Kony and I don't even follow the whole KONY 2012 stuff.
