How Does the Potency of Modern Marijuana Compare to Marijuana From the 1970s?
If you’re wondering how modern marijuana is different from marijuana from the 1970s, you’re not alone. The drug has grown significantly in potency in recent decades. The marijuana samples seized during the 1970s now form the basis for research by the Natural Center for Natural Projects Research, a university-based research group. Researchers measure marijuana’s potency by the concentration of cannabinoids – the chemicals that make it a psychoactive substance – in different strains. ny medical marijuana card expiration
Today, marijuana is more potent than it was in the ’70s, with its THC concentration increasing from 4% to 15%. The most common strains of marijuana now contain anywhere from 50 to 90% THC, or delta-9-tetrahydrocannabinol, the psychoactive ingredient in marijuana. THC levels have been linked to a range of effects on the brain and body. Higher levels of THC can increase the risk of adverse effects.
Since the government has been testing the potency of marijuana for nearly 40 years, researchers have been comparing the THC concentration of marijuana from the 1970s to that of today. However, these studies have been criticized for their methodology, and the resulting average THC readings aren’t necessarily gospel. The size of the samples also varied, but the average THC concentration range was three to four percent. Fortunately, the marijuana industry has moved into a high-tech state and continues to increase its potency.
While this study has been limited to the United States, it highlights some important changes in the marijuana industry. First of all, marijuana’s THC content increased from 4% in 1995 to 12% by 2014, with the addition of CBD. The DEA reported that samples of marijuana over 15% had a THC concentration of 12%. Consequently, modern marijuana is more potent than marijuana from the 1970s.
Secondly, the plants used for marijuana production have changed in several ways. The majority of marijuana in the 1970s was imported illegally from Columbia, which led to oxidation, which decreased the THC level of the plant. Now, people can grow marijuana in a controlled environment, which increases the potency of the average sample. The result is that marijuana is now available in more potent forms – wax, oil, and cannabis extracts.
Another important factor that affects marijuana’s potency is the cultivation process. In the 1960s, cannabis was illegally imported and contained high amounts of THC. It was also grown outdoors, so most marijuana was probably grown in Mexico or Colombia. However, the potency of the plant is much higher today, thanks to better research and public acceptance. There are still a number of factors that affect marijuana’s potency, but the basic difference is the amount of THC in the marijuana.
