Medical experts agree it’s extremely unlikely to fatally overdose on marijuana, but higher THC levels, consumable edibles and laced weed are making it more dangerous.

Marijuana, also known as cannabis or weed, has been subject to much debate over the last couple of decades. One of the most common questions that crops up is can you overdose on marijuana? This is an age-old question pervading discussions of drug overdoses. Pro-cannabis supporters point to arguments claiming that marijuana is perfectly safe to use and has perceived health benefits. On the other side of this debate, opponents assert that marijuana deserves its restrictive federal classification as a Schedule 1 substance by the Drug Enforcement Agency.

No other single drug has nearly as many staunch proponents with such opposing viewpoints. With marijuana becoming legal in several states and available for medicinal purposes in dozens of others, it is certainly a conversation that needs to be had.

Exploring the fundamental question of whether an individual can fatally overdose and die from marijuana overconsumption alone helps drive a productive dialogue in the United States. Additionally, by having such discussions, we ensure that those who choose to partake in cannabis develop safer habits of use that mitigate any potential issues that might arise.

Article at a Glance:

  • Overdosing on marijuana alone, such as from too much THC, is highly unlikely and perhaps even impossible.
  • THC concentrations in marijuana have gotten higher in recent years, making the drug more dangerous and unpredictable.
  • Marijuana overconsumption symptoms include headache, pale skin, paranoia, confusion and increased heart rate.
  • Medical professionals can help people with extreme paranoia and psychosis due to consuming an excess of marijuana.

Can a Marijuana Overdose Lead to Death?

Despite rhetoric from one side or another, one thing remains an objective reality: overdosing on marijuana alone is unlikely, if not entirely impossible. Unlike other drugs that are notorious for binding to areas of the brain that control vital functions like breathing, marijuana mostly affects memory and coordination.

According to reputable sources such as the National Institute on Drug Abuse, there have been no overdose fatalities linked to cannabis alone.

In June of 2019, a Louisiana coroner claimed the first case of a fatal marijuana overdose due to a highly-concentrated THC oil, but medical experts have doubted this autopsy’s findings. Currently, national institutions with the best interests of drug users in mind have noted a fatal cannabis overdose is extremely unlikely.

For the sake of argument, just how much would it actually take to die from marijuana? Best estimates put the amount needed at 1500 pounds of cannabis ingested in 15 minutes.

Is Too Much Marijuana Dangerous?

Some more recent recreational trends have shifted the danger conversation slightly. Tetrahydrocannabinol, or commonly referred to as THC, is the main psychoactive component found within cannabis.

Over the last decades, THC levels have increased exponentially across marijuana strains the world over. This, paired with newer means of ingestion such as dabbing and edibles, means that marijuana use has become somewhat less predictable than the otherwise benign methods of smoking.

Dabbing involves smoking a high concentrated hash or wax to attain an instant, intense high. As the name implies, edibles involve the creation of food products such as candies or desserts with THC baked in.

The true problem resides in dosages. To this day, many states still lack regulations of THC levels for edibles. Approved sellers are left to mostly play a guessing game when it comes to advertising THC content of their products. For the novice, this can have hazardous effects. Edibles also have a slower absorption time, so a person could ingest large amounts of THC without realizing it before the effects begin.

Take Colorado, one of the very first states in the country to legalize recreational marijuana use. A chief issue facing Colorado dispensaries revolves around marijuana tourists coming from outside states. These people then consume dabs or edibles while incorrectly assuming that these products contain the same THC levels they are accustomed to.

While the term ‘marijuana overdose’ may be too extreme even in these instances, there have certainly been many documented cases of people needing medical attention after getting too high, too quickly.

Other Risks and Dangers

The term ‘gateway drug’ is often used as a trope when discussing marijuana use. This is because using marijuana does leave people susceptible to unknowingly ingesting other substances. Experts have long warned of the dangers of cannabis being laced with harmful drugs such as PCP, crack or cocaine. Any drug purchased off the streets can come with more than what one may have bargained for.

Marijuana Overdose Symptoms

Though not necessarily symptoms of an overdose leading to death, there are without a doubt signs of marijuana overconsumption. Such symptoms may include:

  • Escalated heart rate
  • Headache
  • Pale skin
  • Paranoid thoughts or hallucinations
  • Confusion or panic attacks

Symptoms like the ones described here should not be ignored under any circumstances. Do not let the fact the symptoms originated from cannabis prevent you from seeking help. Always seek medical intervention if it becomes necessary.

Marijuana Overdose Treatment

Treating marijuana intoxication is typically a waiting game. Seeing as paranoia or psychosis may occur in the most extreme scenarios, it is important to soothe, reassure and put the affected individual in a comfortable environment, preferably with medical professionals nearby to help.
