  5. There are over 2,000 chemical compounds in marijuana once it is lit. • THC is the main active chemical and is stored in fat cells for long periods of time (stored up to 30 days) • THC can also be stored in brain, lungs, ovaries, and testes. • THC content is rising • 1960’s THC level = 1-2% • Today THC level = 21% • It is stronger and more damaging!!!

  7. Long Term Effects • Many of the same respiratory problems that tobacco smokers have • Cancer of the respiratory tract and lungs may also be promoted by marijuana smoke. • 50 percent to 70 percent more carcinogenic hydrocarbons than tobacco smoke

  8. Quick Facts • Reaction time for motor skills, such as driving is reduced by 41% after smoking 1 joint and is reduced 63% after smoking 2 joints • average age of first trying marijuana is 14 years old!!! • The daily use of 1 to 3 marijuana joints can produce the same lung damage and potential cancer risk as smoking five times as many cigarettes

  9. Marijuana and Addiction • Raises levels of dopamine-produces a pleasurable feeling. Can be intense. • Can wear off dramatically-Crash • Users get addicted to the dopamine release (intense pleasurable feeling)

  10. Physical Consequences • Teens especially-reproductive organs • Males-sperm production and testosterone levels lower • Females- raises testosterone levels
