How can you tell if someone is on meth when they are just starting off?

It's very unlikely.: It is so difficult to tell when someone is just starting. I hope you're a good friend who will watch out or if it's yourself, you will try and stop. It's easy at the beginning. All the best.

Meth addiction: Signs include flushing, dilated pupils, hyperactivity, restlessness, sweating, twitching, tremors, irritability, paranoea.
