with no tolerance, 15mgs adderall xr was too much for me to take for therapeutic purposes

try 10 mgs then 15 when that stops working for the adhd

its also a good remedy for weed burnout

btw xrs are horrible to snort anyway, i did a couple of times and i ended up with a sore throat and post nasal drip that lasted over a week, instead powder and mix it with a drink if u want instant release
dont snort pills ppl!

seriously though... thc is the best med of all!
