My friend went a little crazy on New Years and took 270mg of Adderall IR over a 14 hour period. She also smoke a lot of weed and drank some too. She knows it was stupid, she wouldn't recommend it but she really did have a lot of fun. She has no tolerance for Adderall and it is the first time she has taken it in years (even in the past it was only 30mg). In order to be as safe as possible when doing such a large amount she was sure to only take 15-30mg at a time and wait at least and hour and half before each redose. I am wondering how similar such a massive amount of Adderall (for someone who has no tolerance) is to meth or speed. Obviously it was a crazy Addy high but I am wondering what amount of meth this would be equivalent to, if at all. Maybe her Addy high would be similar to a moderate meth high? Or for example, she took 270mg of Adderall but maybe it is only equivalent to 100mg of meth (I am just making that figure up). Please no lectures. It wasn't the smartest idea but she is safe and didn't even experience more than a few hours of a negative comedown or "hangover". She will likely do Adderall in the future, but never again in such large amounts.
