Marijuana comes from the dried flowers of the plant Cannabis sativa and it contains more than 500 chemicals. Cannabis can have a mind-altering effect on a person.

THC or delta 9-tetrahydrocannabinol is the major psychoactive agent in marijuana. When you smoke cannabis, THC goes from your lungs into your bloodstream and then into your brain. It triggers the part of your brain that responds to sources of pleasure, thereby releasing a chemical called dopamine, which causes the “high” feeling.

The effect of THC can vary depending on who you are, the force of the strain, whether you smoke it or eat it, and other things. It can:

  • Amplify your senses
  • Give you a relaxed sense of happiness and security
  • Change your sense of time
  • Make you hallucinate
  • Make you anxious, afraid, or panicked

CBD or cannabidiol, is another compound in marijuana. It doesn’t make you high. Instead, it can stabilize the effects from THC and bring you down from any paranoia.
