Exploring cannabis for the first time can be a lot to take in. Whether you’re curious about its recreational effects or seeking therapeutic benefits, understanding cannabis strains is the first step to a safer and more enjoyable experience.
In this guide, we’ll walk you through the three main cannabis strains—Sativa, Indica and Ruderalis—and explain how each affects the body and mind. With UK laws shifting and access improving, knowing the difference matters more than ever.
Hemp is part of the Cannabis Sativa family but is grown specifically for industrial use. It contains minimal THC (the compound responsible for feeling “high”) and is rich in CBD, which is non-intoxicating and offers several wellness benefits.
Unlike cannabis sold in UK dispensaries or on the black market, hemp is legally available across the UK. Many wellness products—like CBD oil, skin balms and capsules—use hemp-derived extracts. However, it’s important not to confuse these with cannabis strains intended for recreational or medical use.
Cannabis Sativa is a tall, narrow-leaved plant that thrives in warm climates. It has a longer flowering cycle, often taking up to six months to fully mature. Sativa strains typically contain higher CBD to THC ratios, offering an energising, cerebral high that enhances focus, creativity, and motivation.
Therapeutic benefits may include:
Reduced anxiety and depression
Improved appetite
Relief from nausea, migraines, and muscle cramps
Enhanced concentration and alertness
Sativa is popular with creative professionals, daytime users, and those seeking a boost without heavy sedation.
Cannabis Indica originated in the mountainous regions of Central and South Asia. These plants are short and bushy, with broad leaves and a faster flowering time compared to Sativa.
Indica strains are often chosen for their body-focused effects. With higher THC content, they tend to provide deep relaxation, making them ideal for evening or bedtime use.
Potential benefits include:
Chronic pain relief
Muscle relaxation and spasm reduction
Help with insomnia and anxiety
Easing inflammation-related discomfort
Indica is widely recommended for stress relief and managing symptoms of autoimmune or neurological conditions.
Cannabis Ruderalis is lesser-known but highly valuable in breeding programmes. It’s a tough, fast-growing strain that thrives in extreme climates and flowers automatically—regardless of light cycles.
On its own, Ruderalis has very low THC and limited psychoactive effects. However, its genetics are used to create “autoflowering” hybrids that are easier and quicker to grow.
If you’re new to cannabis, choosing the right strain can make all the difference. Here are a few beginner-friendly options widely available in the UK:
Smooth, mellow and sleep-inducing—great for relaxation without overwhelming effects.
Low THC and high CBD make this ideal for pain relief and anxiety without strong psychoactive effects.
Perfect for users seeking full-body relaxation without a head high—ideal for medical use.
Delivers a clear-headed buzz with creative energy, without anxiety or paranoia.
A potent yet calming strain that pays homage to cannabis’ ancient roots.
Eases beginners into higher THC content with a gentle onset and enjoyable body effects.
Known for its sweet berry aroma and balanced high—uplifting for the mind and relaxing for the body.
This guide highlights some of the most accessible and user-friendly strains available, but the world of cannabis is constantly evolving. Breeders continue to develop new hybrids and variations that balance potency, flavour, aroma, and therapeutic effects.
Whether you’re based in London, Manchester, or Glasgow, make sure to seek guidance from trusted sources and UK-registered cannabis clinics or CBD retailers. Explore safely, understand what you’re consuming, and find the right strain that works for your needs.
