Substance abuse disorders starts with addiction, then graduates into tolerance and later withdrawal

Explanation:

Substance use disorders or drug addiction, is a behavior that leads to inability to control the use of a drug or medication.

ADDICTION: When you are addicted to substances like marijuana or alcohol, it makes you continue in the use of these drugs not minding the harm they cause.

TOLERANCE:Tolerance occurs when people's response to the drug begins to decline from the way it happened at first, leading them to needing higher doses in the pursuit of the initial level of gratification.

WITHDRAWAL: This is more like a secondary consequence of the drug which strikes at the attempt to stop (withdraw) from the drug use. It leads to illness, sleeplessness, prolonged malnutrition and pain.
