How to Use a 510 Cartridge or Vape Pen in Johannesburg

By Green Vault Editorial Team · Published 2026-10-27

What Is a 510 Cartridge and Why Does It Matter?

A 510 cartridge is a pre-filled cannabis oil tank designed to screw onto a standard 510-thread battery. The "510" simply describes the thread specification — 5mm, 10 threads — and has become the universal standard for vape hardware. This matters because it means most cartridges and batteries are interchangeable, making it easy to swap flavours or strains without buying new hardware each time.

Disposable vape pens combine the cartridge and battery into one unit, designed for single use. Rechargeable vape pens use a built-in or replaceable battery with a USB charging port and accept replaceable cartridges. Both are widely available, and both have legitimate use cases depending on your lifestyle and consumption habits.

How to Use a 510 Vape Pen: Step by Step

1. Check the connection Screw your 510 cartridge onto the battery gently — finger-tight only. Over-tightening can damage the threading or the cartridge's heating element.

2. Charge the battery first (rechargeable pens) A flat battery produces weak, uneven vapour. Charge fully before first use.

3. Prime the cartridge If it's a new cartridge, take one or two short dry pulls (without pressing the button) to draw oil into the coil. This prevents dry hits.

4. Start with a small puff Press the button (or simply inhale on draw-activated devices), take a 2–3 second draw, and inhale slowly. Do not hold vapour in — it does not meaningfully increase effect and irritates airways.

5. Wait before redosing With high-potency THC cartridges, effects can take 5–15 minutes to fully register. Wait before taking another puff. This is especially important with 90% THC products.

6. Store correctly Keep cartridges upright, away from direct sunlight and heat. Extreme temperatures degrade oil quality and can cause leaking.

Understanding THC and CBD Content in Vapes

THC (tetrahydrocannabinol) is the primary psychoactive compound. CBD (cannabidiol) is non-intoxicating and is often associated with a more measured experience. Most vape cartridges on the market are THC-dominant.

Potency matters. A 90% THC vape cartridge — like the Blue Dream Disposable Vape Pen (Hybrid, R450) or the Lemon Haze Rechargeable THC Vape (Sativa, R450) available at Green Vault — delivers a very concentrated dose per puff. These are not equivalent to smoking flower. New users should approach high-potency cartridges with particular caution.

Some users report that Sativa-leaning vapes feel more energising and cerebral, while Indica-leaning options may feel more body-focused and calming. Hybrid cartridges sit somewhere in between. These are general tendencies, not guarantees — individual response varies significantly.

Comparing Vape Types: Disposable vs Rechargeable vs Liquid Diamond

Liquid Diamond vapes use a more refined extraction process that preserves a broader terpene profile, which some users report results in a richer flavour and more nuanced experience compared to standard distillate cartridges. The Durban Poison Berry Bhang Bar 2g (Sativa, R1250) is a good example of a locally-inspired strain in this format.

Strain Types and What They Mean for Vaping

Choosing the right cartridge isn't only about hardware — the strain type and terpene profile shape the experience considerably.

• Sativa strains (e.g. Lemon Haze, Durban Poison, Ghost Train Haze) are commonly associated with more uplifting, daytime-friendly effects. Some users report increased focus or creativity.
• Indica strains (e.g. Grape Ape, London Pound Cake, Banana OG) are often described as more relaxing and body-oriented. Many users prefer these for evening use.
• Hybrid strains (e.g. Blue Dream, OG Kush, Skunk Slushie) blend characteristics of both and tend to be versatile.
• CBD-dominant products offer the non-intoxicating profile and are worth considering if you are sensitive to THC or new to cannabis.

Never make purchasing decisions based on expected medical outcomes. Cannabis affects everyone differently, and no product should be used as a substitute for professional medical advice.

Red Flags to Avoid When Buying Vapes in Johannesburg

The Johannesburg market — like any urban cannabis market — has its share of unverified products. Here is what to watch for:

• No lab testing information. Reputable sellers provide cannabinoid content data. If a seller cannot tell you the THC/CBD percentage or confirm independent lab testing, do not buy.
• No age verification. Any platform selling cannabis products to adults in South Africa should verify that buyers are 18+. Absence of age checks is a serious red flag.
• Unusually low prices with no product information. Counterfeit cartridges exist and can contain harmful cutting agents. Price alone is not a quality indicator, but suspiciously cheap unverified products warrant scepticism.
• No secure payment process. Green Vault uses secure online card checkout in ZAR. Avoid sellers asking for cash transfers to personal accounts with no paper trail.
• No discreet packaging. Privacy matters. A trustworthy online dispensary ships in discreet, unmarked packaging.

South African Legal Context — Know Your Position

The Constitutional Court's 2018 judgement decriminalised the private use, possession, and cultivation of cannabis by adults. The Cannabis for Private Purposes Act, signed in 2024, provides further legislative framework. However, commercial sale and supply remains regulated, and the legal landscape continues to evolve.

Always verify the current legal position yourself before purchasing or using cannabis products. This article does not constitute legal advice. Green Vault operates as a licensed online store; purchasing from a compliant, licensed retailer is the responsible choice for Johannesburg adults navigating this space.

Buyer Checklist: Before You Purchase a Vape Cartridge

Use this checklist before completing any vape purchase:

• I am 18 years of age or older
• The seller has verified my age
• The product lists THC/CBD content clearly
• Lab testing information is available or disclosed
• The seller uses secure payment (not personal EFT)
• Discreet packaging is confirmed
• I understand the potency (e.g. 90% THC is high — start slow)
• I have chosen a strain type appropriate for my intended use
• I am consuming in a private setting in line with South African law
• I have checked current regulations independently

Vaping cannabis is a convenient, controlled-dose format that suits many adult users — but it requires the same informed, cautious approach as any potent product. Buy from verified sources, start low, and prioritise your own safety above all else.
