Caffeine is a stimulant. All stimulants are addictive. Therefore caffeine is addictive. If addictive means unsafe, caffeine (see coffee) is unsafe, and not suitable for the general public, as you yourself said about ephedrine. This is what your argument/logic says, point blank.
You don't even know what you're saying, or at least don't know the implications of what you say. Just quite while you can maintain some basic perception of intelligence man.
You can find people addicted to ephedrine "everywhere?" GTFOH with that BS.
THE VAST MAJORITY OF PEOPLE CAN USE EPHEDRINE RESPONSIBLY, DAILY, MULTIPLE TIMES PER DAY, FOR MULTIPLE MONTHS AND NOT NEED TO ESCALATE THE DOSE OR BECOME ADDICTED OR SUFFER WITHDRAWLS. THIS IS CLEARLY NOT THE CASE FOR FREAKING COCAINE. YOU'RE WRONG...
