What is a warning sign of substance abuse?

Those with substance use disorder (SUD) often try to hide their symptoms and downplay their problem

Explanation:

Memory loss, confusion and muscle in-coordination are common signs of alcohol or drug abuse at any age. Do not accept these as normal in older people! Again, many of these “Red Flags” or indicators of possible addiction may be caused by other things.

Physical warning signs of drug abuse:

Bloodshot eyes, pupils larger or smaller than usual.

Changes in appetite, sleep patterns, physical appearance.

Unusual smells on breath, body, or clothing, or impaired coordination

there are men and women, some choose to be both or change their gender. often times those people go by "other". those who change their gender are known as "transgender"
