    Thanks to legalization, many boomers are reliving the pot-smoking days of their youth. But plenty of our parents’ generation are shocked to discover the strength of today’s bud.

    If you started smoking weed Y2K, you’ve probably tried some seriously strong stuff. The strongest strains available today can contain over 30 percent THC. That’s some potent flower.

    While high-THC strains can be too much for some folks, stronger strains are hugely popular among cannabis connoisseurs. If you're looking for an intense, all-consuming experience, you have plenty to choose from. We’ve curated a list of THC-rich options, fresh from the Origins vaults.

    Why does THC Content Matter?

    THC (tetrahydrocannabinol) is responsible for most of the psychoactive effects of cannabis. Cannabis strains with low or no THC can be great for medicinal purposes. But, if you’re looking to get high, you’ll need some THC.

    THC content is measured as a percentage of the total amount of cannabis. It typically ranges from 0 to 30 percent. A strain with 0 to 10 percent will have mild psychoactive effects, while a strain with 20 to 30 percent THC will cause a strong, intense high.

    Today, most strains fall somewhere between 10–20 percent.

    Remember, cannabis doesn’t affect everyone in the same way. If it’s your first time smoking, a strain with 10 percent THC content might pleasantly knock you out. But a long-time consumer might need more than 20 percent THC to get the high they’re looking for.

    The Entourage Effect: CBD and Terpenes

    THC isn’t the only thing that affects the high you experience from a particular strain. Other cannabinoids (like CBD or CBN) and terpenes (aromatic chemicals) work together with THC.

    That’s why two strains with the same THC content can still have very different effects. One might make you deeply relaxed and couch-locked, while another gives you an invigorating, creative rush.

    If you love THC, but need to downplay some of the more anxious side effects look for strains with a higher ratio of CBD and other cannabinoids.

    Has Cannabis Become More Potent?

    There’s evidence to suggest that cannabis has become much more potent over the last 20 years. In 1995, the average THC content of samples was 4 percent. By 2014, it had risen to 12 percent. At the same time, CBD content has decreased.

    So your dad is right: smoking weed isn’t what it used to be!

    Legalization has led to more US-based growers competing to create the best, most potent, and most popular strains. This means it’s much easier for consumers to get their hands on the strong stuff today.

    Our 6 Favorite High-THC Strains

    If you’re looking for hard-hitting strains to knock you off your feet, look no further than these six perennial favorites.

    1. Gorilla Glue #4 (GG4)

    Gorilla Glue #4 is a true classic strong cannabis strain. It’s one of many Gorilla Glue strains and averages between 20 to 25 percent THC.

    A hybrid with sativa-dominant characteristics, GG4 causes a deeply relaxing body high and a serious head buzz. Don’t expect to get much done: Gorilla Glue is strictly for when you need to chill.

    2. Slurricane

    Grab your duvet and prepare for the perfect night in with Slurricane. This indica is known for causing serious couch-lock; you might find yourself asleep before too long.

    A relative newcomer, it’s properly potent, with 21 to 24 percent THC. Slurricane should leave you feeling euphoric, but take it easy if you’re new to weed, as its effects are intense.

    3. Wedding Cake

    Wedding Cake is another strong indica that’s gained a following in recent years. Containing around 25 percent THC, Wedding Cake has a sweet, rich flavor and potent effects.

    The high is balanced though: You’ll feel uplifted and “tuned in” while your body enters a deep state of relaxation.

    4. Blue Dream

    Blue Dream is legendary on the West Coast. So legendary, in fact, that its actual origin story has been lost. That doesn’t stop it from being a favorite of cannabis-lovers across the country.

    Ranging from 17 to 24 percent THC, Blue Dream is a sativa that lends itself to creativity and focus. It also contains relatively high CBD content, which makes it a good choice for medical users.

    5. GMO Cookies/Garlic Cookies

    Pungent, potent, and long-lasting, GMO Cookies is an indica-dominant hybrid you won’t forget. Also known as Garlic Cookies, you can guess what it tastes like!

    Expect an intense high, as this strain averages 26 percent THC. Consumers report feeling overwhelming relaxation, euphoria, and a sense of calm.

    6. Do-Si-Dos

    We’ll finish with a true hard-hitter: Do-Si-Dos can contain up to 30 percent THC. Its earthy, floral scent is uplifting, a sign of things to come.

    Do-Si-Dos will give you a heavy, energizing buzz to begin with, perfect for concentrating and creating. Gradually, the body high will overcome you with a feeling of pure relaxation.
