Marijuana
Marijuana is usually smoked using cigarette rolling papers, a purchased water bong, or a makeshift bong that can be made from a variety of items. Hash can be smoked or eaten, and is sometimes cooked into baked goods.
What to Look for:
Dilated (large) pupils
Cigarette rolling papers
Seeds that have been cleaned from marijuana
Smell on clothing, in room, or in car
Bloodshot eyes
Sleepy appearance
Reduced motivation
Pipes, bongs, homemade smoking devices (you may see sticky residue from burned marijuana)
Generally it can be difficult to recognize marijuana use if you don't see your child after smoking when they are still experiencing the effects of the drug. The potency of marijuana has increased exponentially in the past 20 years.

"Adolescents are particularly at risk of adverse reactions from hallucinogen use as they enter puberty, a time of rapid physical and emotional changes. Hallucinogens are particularly dangerous because the effects are so unpredictable. They can cause violent behavior in some and suicidal tendencies in others. As memory, perception, and judgment are clouded under the influence, users are at risk of severe injuries, overdose, and death from drowning, burns, falls, and car accidents. Sometimes, hallucinogen use can uncover severe mental disorders, such as schizophrenia or severe depression." Texas Commission on Alcohol and Drug Abuse.
