THC is the psychoactive cannabinoid, that makes marijuana users high. If marijuana contains very little of THC, can it still be an enjoyable experience? With these 6 strains on offer, with a THC content of 1% or less, the answer is – absolutely.

Cannabis contains over a hundred chemicals called cannabinoids which latch onto cannabinoid receptors in the human system. What a happy coincidence of evolution! These can have all sorts of effects, the most famous of which is the high tetrahydrocannabinol, or THC, brings. THC also has medical applications as a painkiller, appetite stimulant and muscle relaxant.

The scramble for strains of higher and higher THC potency however, has led to concerns over excessive THC levels, that are not always desirable. Another cannabinoid, cannabidiol (CBD) does not produce a psychoactive high. When CBD interacts with cannabinoid receptors, it may have a beneficial effect on body and mind.

A more moderate amount of THC is advisable because of the biphasic effect. This is when something, that might be pleasant and beneficial in moderation, loses its benefits when taken in excess. This certainly applies to THC, which could dull your ability to feel high from moderate doses, if you're too used to chasing THC-rich strains. A greater balance between THC and CBD boosts the effectiveness of each chemical. Yet there are now more and more strains available which have a THC content of only 1% or less.

THE IMPACT OF HIGH-CBD, LOW-THC STRAINS

The Impact Of High-CBD, Low-THC Strains

1% THC content is quite low, when 15–20% and upwards is what tends to be considered high THC content. Such strains won't bring you a high, but you will feel the serene calming effects of CBD. Let's look at the advantages of a low-THC strain. The calming experience of a CBD-rich strain is very focusing. It's not the psychedelic stoner's high, but it is a like a turbocharged version of all the herbs and incense reputed to be relaxing. CBD is so calming, it is even believed to have antipsychotic properties. It also has a positive impact on the immune system and the connectivity of the nervous system.

CBD is said to help with the healthy regulation of the nervous system. If your thinking lacks clarity, perhaps the neurons in your brain will be more fluidly connected with some good CBD. It can take the edge off and relieve pain, but without the mind-altering state THC delivers. This could be important for therapeutic users, especially ones pursuing a full life, that doesn't allow much time for getting high.

6 Cannabis Strains With 1% THC Or Less

One wouldn't need to plan their day around getting high if it's not the sort of high, that will floor them with sedative indica properties. The buzz of a sativa is also intoxicant in a way that can be temporarily hampering. A high-CBD strain allows you to smoke more often and get the medical benefits with a smoother, more relaxing sensation. Here are 6 on offer from the world's best seed banks.
