Tolerance and dependance

Anyone can develop a tolerance to speed, base or ice. Tolerance means that you must take more of the drug to feel the same effects you used to with lower amounts.

Dependence on a drug such as methamphetamine means that it takes up a lot of your thoughts, emotions and activities. You may also have trouble cutting back on your drug use even though it is causing you problems. Dependence on speed, base or ice can lead to a variety of health, money, legal, work and relationship problems. Not all people who use methamphetamine are dependent.
