Marijuana: What Is It?

Marijuana is a hemp plant whose biological  name is cannabis sativa. It consists of green, brown, or a grey mixture of dried, shredded leaves, stems, seeds, and flowers. 

THC (delta-9-tetrahydrocannabinol) is the primary mind-altering ingredient in marijuana.

Cannabidiol (CBD) is a compound in cannabis that has medical effects but does not make people feel “stoned” and can actually counter the psychoactive effects of THC.

 

How is it used?

  • Smoking – joint, blunt, vaporizer, Dab, spliff, bowl, bong (5-90+% of THC absorbed)
    • When smoked the absorption of THC is rapid – THC is distributed to various organs especially those with high concentrations of fatty material (brain, placenta)
  • Oral – medicinal – Marinol (pill) – effects last longer than smoking
  • Eating – edibles – can be more potent than smoking

 

What happens when you use marijuana?

  • Behavioral affects occur immediately and last up to 2-3 hours unless more is smoked
  • THC is stored in body fat from which it is slowly released – users with more body fat tend to get “higher” faster on subsequent uses

 

 Frequency of Use

  • Infrequent smokers - < 2x per week, urine samples positive for 3-7 days
  • Regular smokers – 2-5x per week, urine positive for 7-21 days
  • Chronic smokers – daily, urine positive for 30+ days
