Feeling happy after cannabis use might be just a personal state of mind, while some researchers are studying how the plant interacts with mood and the nervous system. But does weed actually make us happy, and how would that work?

Key Takeaways

Both THC and CBD may affect mood by interacting with the brain and the body. However, the two interact differently, which produces different effects. THC is the most widely known for its psychoactive effect, the euphoria many users describe. CBD is non-intoxicating and is more often discussed in relation to calm than to that euphoric feeling.

What Science Says About ‘How Weed Makes You Feel Good’

Has weed ever made you laugh uncontrollably after smoking a joint? That’s because cannabis stimulates blood flow to the frontal and temporal lobes of the brain which are the areas responsible for humor processing. Weed also stimulates chemicals that cause the release of hormones that are known to make you happy and put you in a cheerful mood, serotonin and dopamine.

Let’s dig in a little deeper into these two hormones:

Dopamine, The euphoria happens when THC binds to the cannabinoid receptors, resulting in a flood of dopamine within the brain that makes any activity, including eating and relaxing, more enjoyable.

Serotonin, This hormone is a neurotransmitter that affects many processes in the mind and body. It is also studied alongside CBD, since serotonin levels are part of how researchers describe mood regulation.

What’s more, the godfather of weed known as Dr. Raphael Mechoulam has discovered that a neurotransmitter called anandamide is the reason why weed makes stoners so happy. The name “anandamide” has the word “happy” (kind of) hidden within its name. The word derives from a Sanskrit word, ananda, which means “happiness” or “joy”. Anandamide occurs naturally in the human brain and plays an important role in our daily lives to help regulate bodily functions such as movement, emotions, memory, appetite, pain, and motivation. Anandamide is sometimes nicknamed the “bliss molecule” because of the role it plays in mood. This neurotransmitter is also an important endocannabinoid that our bodies naturally produce which also binds to cannabinoid receptors when we use weed.

What we might not know is that THC contains incredibly high concentrations of anandamide. Our bodies already produce our own anandamide, therefore, when we consume weed, it also triggers the release of anandamide. Studies revealed that when THC reaches the brain, it triggers the release of dopamine, also known as the reward molecule. At the time dopamine levels are elevated, the brain’s reward system may cause you to feel extreme satisfaction and pleasure. If the dopamine levels are staying up for too long, the body may shut down some of the dopamine receptors even if you’re no longer high from the THC. As a result, dopamine synthesis in the body may decrease, causing you to have a hard time feeling pleasure from the things that would normally make you happy such as hobbies and food.

Which Strains Do People Associate With a Happy Mood?

The strains below are ones people often associate with an uplifting, sociable mood. Each has its own aroma and reported character, and the way any strain affects a person can vary a lot from one individual to the next.

Blue Cheese

Blue Cheese is an indica hybrid created by crossing Blueberry and Cheese strains, producing a blend of blueberry and cheesy aromas. It has a moderate THC content, roughly 15% to 20%, and a profile people often describe as relaxing, which is why it tends to be associated with evening use. Beyond that, people who have tried Blue Cheese have reported effects such as euphoria, happiness, sleepiness, and hunger. Reports like these are personal experiences and are not medical claims.

Cherry Burst 

Cherry Burst is an Indica-dominant hybrid made by crossing two genetics, Tropicana Cherry and Super Buff Cherry #26. As its name suggests, it is a popular pick among Indica lovers who enjoy sweet and sour berries with a touch of spicy skunk taste. Cherry Burst is often described as an uplifting, giggly mood that can leave you laughing. As with any strain, reported effects are personal and vary from one person to the next.

Orange Fanta

Orange Fanta is a well-known 50/50 hybrid created by Seattle Chronic Seeds by crossing Agent Orange and Hindu IBL strains. It has a fruity flavor and aroma, and many describe its effect as long-lasting and uplifting. People who have tried it often mention a brighter mood, though, as with any strain, individual experiences vary.

Purple Pineapple 

Purple Pineapple is an Indica-dominant hybrid with a tropical aroma, bred for its aroma and uplifting character. It is often associated with a sociable, talkative mood. It has a musky sweet aroma with a sweet grape and pineapple flavor. As with any strain, reported effects are personal and vary from person to person. 

Sour Diesel

Sour Diesel is a well-known strain among enthusiasts, recognized for its iconic diesel scent. It was made by crossbreeding Chemdawg and Super Skunk, and it is often described as producing dreamy, cerebral, and energizing effects.

Conclusion

The reason why weed makes us feel happy has already been explained by scientists and researchers. It’s mostly associated with three main chemicals including dopamine, serotonin, and anandamide. When we use weed, it triggers the release of two happy hormones, dopamine, and serotonin, as well as a neurotransmitter, anandamide which regulates our happiness. Five strains people commonly associate with an uplifting mood are Blue Cheese, Cherry Burst, Orange Fanta, Purple Pineapple, and Sour Diesel.
