B4 is a hybrid strain of cannabis created by crossing parent strains Blue Dream with Chemdawg 4. B4 tends to be a balanced hybrid, with around 50% sativa and 50% indica genetics. The strain is potent, with a high THC level of up to 26%, and reportedly induces feelings of euphoria, heightened awareness, and a dreamy, full-body buzz. B4 may be beneficial for managing stress, anxiety, depression, and chronic pain.

The B4 strain was created by MTG Seeds, who also produced the famous Orange Creamsicle.

B4 is a colorful and attractive plant bearing small-to-medium forest green buds with fiery orange hairs, light blue undertones, and a coating of gold trichomes.

This strain is famous for its earthy, blueberry scent. Its potent effects combine the common wide-awake, creative effects of sativa strains with the more relaxing, happy high of indica strains.

Terpenes are naturally occurring compounds found in trace amounts in cannabis. They’re located in the trichomes of cannabis plants and contribute to their pigmentation and the unique aroma of the bud.

Levels of terpenes are variable, as they depend on many factors, like whether the plant is grown indoors or outdoors, how much it’s exposed to light, its nutrient levels, and when harvesting occurs.

B4 users report the initial effects of increased blood pressure in the head, flushed cheeks, and increased salivation. As the sativa side of B4 kicks in, users notice that thought processes start to change, focusing on new ideas and concepts. Some people even find that B4 gives them a creative boost while at work, and it can make domestic chores like the laundry or the dishes a bit more enjoyable.

After this phase, common indica effects take over, relaxing the whole body and bringing a feeling of euphoric bliss. B4 is more suitable for the afternoon or evening than earlier in the day, as users begin to “crash” and may want to chill out on the couch after a while.

B4 can induce altered thought patterns, so one adverse side effect of this strain is feelings of paranoia in some people. If you are prone to panic or are an inexperienced cannabis user, it is best to steer clear of this strain.
