Warning Signs of Marijuana Use

If someone is high on marijuana, he or she might

• seem dizzy and have trouble walking;
  
  
• seem silly and giggly for no reason;
  
  
• have very red, bloodshot eyes; and
  
  
• have a hard time remembering things that just happened.
  
  

When the early effects fade, over a few hours, the user can become very sleepy.
