Yes. Meth use can quickly lead to addiction. For one thing, it causes tolerance: People who get addicted to meth start needing to take more of it to get the same high. People who usually eat or snort meth might start to smoke or inject it to get a stronger, quicker high.
People who are trying to quit taking meth might:
- Get really tired but have trouble sleeping.
- Feel angry or nervous.
- Be unable to feel happy.
- Feel a very strong need to take meth.
