Dose - Intravenous doses- clarifications needed

[TheBlackPope]

Alright, the sticky had too many hypocrisies in it and Swim would like to ask some questions about the intravenous use of cocaine.

When swim obtains a gram of cocaine, he splits it into 4 lines (.25g) and snorts them all in 10-15 minutes.

If swim was to intravenously use, would their be a problem w/ shooting a whole line (.25g) and calling it a day?

The sticky said .05g was "pushing it", and swim thinks this is ridiculous. If swims normal dose is 1.00g of cocaine intranasal, why would he need 1/20th of his normal dose and be "pushing it"? It just seems like they've never done it and are saying it to be cool on an internet forum.

So, for anyone who has actually shot cocaine, not anyone else, what is a good dose for 1 shot only, not multiple shots, just one.

Also, what is the difference between shooting cocaine compared to methamphetamine or OxyContin? Should I expect my arm to go numb?

What else should I expect? It seems uncomfortable.
