Sativa strains are generally better for recreational use, with sativa dominant high THC strains like Green Crack x Super Silver Haze inducing a strong yet creative and cerebral high which can benefit consumers who are artists, musicians or work creative jobs greatly while also being good for smokers who want to remain active whilst also being high.


While Indica dominant strains like Yumbolt Feminized have the highest THC content (24%) which is well suited to medicinal purposes or general relaxation. Both Sativa and Indica can be used for medicinal purposes with Indica generally having more benefit for physical problems than Sativa.


Many of the strains with the highest THC percentages are hybrids, meaning they exhibit traits of both Sativa and Indica marijuana.

How Long Does the 'High' Last?

Marijuana with the highest THC content is naturally very potent but the effects can vary. The duration of the high largely depends on which of the high THC seeds you choose to cultivate and also how you consume it. 


Take a classic like Gorilla Glue #4 Feminized Marijuana Seeds which is among the highest THC strains of marijuana for sale at Homegrown Cannabis Co.  When smoked or vaped, the high may last for around 4 hours, naturally this can change depending on the quantity you consume. As Kyle Kushman says in his Gorilla Glue Feminized Marijuana Strain Profile, the high is fast acting and can have an extremely positive effect on your mental state. Furthermore, Kyle also picks Gorilla Glue #4 as one of the top high THC cannabis seeds for novice growers.


Here are a few examples of how to consume the highest THC percentage marijuana:

  • Inhalation. Vaporizing or smoking the buds are generally the most popular ways of dosing cannabis with high THC levels. The effects are fast acting - usually within 15 minutes - because the THC goes straight into the bloodstream. However, the high lasts only 2 to 4 hours. It is preferred for casual use, brightening up the day with a puff or two. Also, it is suitable for medical patients who are unable to ingest food or liquids.
  • Ingestion. Making THC edibles is becoming an increasingly popular way of consuming THC. Adding THC to sweets, baked goods or smoothies are just some of the enjoyable ways of dosing. Ingesting THC prolongs the high, meaning it could last for up to 8 hours. This makes it perfect for medical use as it can provide long-lasting relief.
  • Sublingual application. Another widely used method of consumption is dropping small amounts of tinctures under the tongue. The psychoactive effects become apparent after 5 to 10 minutes and can last 2 to 4 hours. It is by far the simplest way of dosing but entails enduring the tincture's bitter taste.
