Rising THC levels in marijuana: A Rising Concern

The Evolution of Cannabis Potency

Since the 1970s, the psychoactive compound has been rising THC in marijuana has been steadily increasing. This rise in potency is largely due to growers selecting for more potent strains. With the growing acceptance and legalization of cannabis, regulators are concerned about the potential risks associated with stronger cannabis.

Potency Monitoring Program Findings

In the US, the Potency Monitoring Program has shown a significant increase in THC levels over the past 50 years. The average THC content in cannabis has risen more than tenfold during this period. This trend is not limited to the US; other countries have also seen an increase in THC concentrations.

Breeding for Potency

Growers have adopted sophisticated breeding techniques to select for more potent strains. Seedless cannabis, or sinsemilla, is a prime example. These unpollinated female plants produce buds and flowers with high levels of THC-rich resin, sometimes containing twice as much THC as regular seeded varieties.

Changing Consumption Patterns

While dried flower remains the most common form of cannabis consumption, other methods such as edibles and vapes are gaining popularity. These forms of consumption can contain higher levels of THC. Some concentrates, for example, have THC levels of up to 90%.

The Risks of High THC Levels

The availability of highly potent marijuana raises concerns about potential side effects. Higher THC levels can lead to unpleasant or dangerous effects such as nausea, vomiting, paranoia, and abnormal heart rhythms. Despite cannabis’s long history of use, the strains available today are significantly stronger, leading researchers into uncharted territory regarding its safety.
