Marijuana is one of those substances that gets touted on as the safest drug on the market by its users. Is that really true that marijuana has no comparable effects to those associated with tobacco and alcohol like cancer or death? Yes. The amount of research done on this topic shows no major ill effects are observed directly in a healthy human as a result of cannabis. But what are effects of marijuana on the body?

The first thing to know about cannabis is that there are different kinds of cannabis with distinct effects. Let’s quickly see what the different types are:

  • Sativa: A high THC (psychoactive component that gives you the ‘high’) strain that breeds creativity, sociability and alertness. Typically consumed during the daytime.
  • Indica: A high CBD (non-psychoactive component known for pain-relief and promoting sleep) strain that gives the user relaxed and soporific effects. Typically consumed during the night to reduce insomnia and sleep apnea.
  • Hybrids: A mix of Indica and Sativa due to the cross-pollination of the plants. These strains have the effect of both indica and Sativa. Modern science has made it possible to tweak the amount of THC and CBD in the plant to give specific strains that have better effects.

Known Effects of Cannabis on the Human Body


  • It is known to increase the heart rate of the user for up to three hours post smoking. It is temporary but may affect people who are at risk of heart disease.
  • It is known to cause coughing and increased phlegm when smoked. But these effects are nullified if cannabis is consumed in other methods like edibles.
  • It can cause temporary short-term memory loss in users under 25 years of age. It is recommended to use marijuana after the brain is fully developed which happens at 25 years.
  • Increased doses might increase chances of making users susceptible to paranoia and depression.


  • Sativa dominant strains are known to beneficial for Chronic fatigue, Migraine and headaches, Glaucoma, Depression (in low doses), Focus and concentration and other effects.
  • Indica dominant hybrids are known to be beneficial for Insomnia, Sleep apnea, Chronic pain, lack of appetite, Muscle tensions and spasms, Physical stress and anxiety (in low doses).
  • Hybrids have different effects for different strains. They also are known to reduce common side effects of cannabis like couch-lock or cottonmouth.

These are some effects that marijuana have on the body but is in no way an exhaustive list. More studies need to be underway to once and for all prove cannabis is 100% safe but as it stands now and what we know now, I can say it is safe barring minor side-effects.

PS: Before consuming any kind of substance it is important to do your own research about what you want to put in it. Staying safe is always the number one goal.
