Dose - Concerta Question

[CiphA]

SWIM has been reading these forums for awhile now and has finally decided to make a post. One of SWIM's friends has been prescribed Concerta. SWIM has just been informed of this and SWIM's friend has agreed to give him a fair amount of pills. SWIM has a few questions.

1. If not insufflated and instead taken orally, what would be a sufficient dose to become very focused and work effectively? Also, what would be a good recreational dose? SWIM has read the threads and come across a few possible answers but would like to find out the answer for himself.

2. If Concerta orally is too inefficient for either, SWIM is not totally against the idea of insufflating and would be willing to give it a shot if reassured by SWIY by being given information on advised dosage for above reasons and tips for actually snorting the powder.

SWIM thanks you for your time.
