Canberra - Pharms, Capsules, R30 - What are these?

Hey there,
Some pharmaceutical capsules have become available (not sold as 'ecstasy' or anything though) and I would like to know what is in them. I know they are printed with R30 on the side of them and they are definately produced by a legitamit pharmaceutical company but thats about it. Unfortunately, I haven't seen them with my own eyes or taken any but someone I know who has said they had a speed-like effect. They were given to my friend with the understanding that they would have a "speedy" effect aswell.

If I get more info I'll post it. Any help appreciated.
Thanks in advance.

P.S. Had a look at rxlist, erowid and did a search on these forums but didnt find anything.

It's most likely Ritalin

Ritalin LA 30 mg capsules are white to off-white beads in a yellow capsule with imprint NVR and R30 in tan coloured ink; bottles of 30 capsules.

from Ritalin

From using *R30 capsule* in Google (Aus)

My immediate thought is "ritalin" a drug that has amphetamine like physialogical effects but does not have an amphetamine like molecular structure. It is prescribed generously to peopel with "ADD" "ADHD" and other related symptoms.

However the only ritalin tablets I have seen are found pills with both sides flat


EDIT:
WHOOP: You bet me to it phase_dancer =)
Also dont pay much for them!! They are not anywhere near as pleasent as
amphetamines (Hope that doesnt breach any rules)
