I was recently told by a Doctor that you cannot experience withdrawal from stimulants like amphetamines. She said that if anyone says they are having withdrawal it is not true. Can someone experience withdrawal if they stop taking amphetamines?
Amphetamines can definitely cause withdrawal symptoms. Like other drugs, the severity of symptoms depends on the usage pattern and the particular amphetamine. For methamphetamine, the strongest withdrawal symptoms are from 1 day to 1 week after last use but can continue for weeks afterward.
Like other drugs of abuse such as cocaine and opiates, withdrawal symptoms are thought to be a major (if not the major) contributor to relapse.
Common symptoms of amphetamine withdrawal include depression, dysphoria, anxiety, agitation, irritation, anhedonia, fatigue, sleepiness following by sleep disturbance, increased appetite, concentration problems, and others.
I'm not sure why a doctor (I presume a physician?) would suggest that amphetamines do not cause withdrawal symptoms. It's possible this statement was meant to apply to prescriptions for amphetamines, for example for ADHD, but those drugs can also cause withdrawal symptoms. Giving her the benefit of the doubt, it's possible she was referring to a low dose of an amphetamine that would not be likely to cause withdrawal side effects, and describing them this way was a professional simplification meant to reassure a patient about a particular option rather than make a blanket statement. I don't agree with that approach but I can appreciate the reasons for it, if that was the case.
Otherwise, the idea that these symptoms are somehow "not true" because they are mental symptoms and therefore somehow invalid seems to be a very old and discredited approach to addition, akin to telling a depressed patient there is nothing wrong with them because it's "all in their head."
