THC Vapes vs Flower vs Gummies: Which to Buy in Johannesburg
By Green Vault Editorial Team · Published 2026-09-10 · Updated 2026-10-01
Quick Answer
THC vapes and flower are inhaled and felt within minutes; gummies are eaten, often take 30 minutes to 2 hours and last longer. Choose flower for strain choice, a vape for discretion and small puffs, or gummies for no smoke. Green Vault sells all three online, delivered across Johannesburg, usually in 1 working day.
THC vapes, flower and gummies differ mainly in how you take them, how quickly you feel them and how long they last. Flower and vapes are inhaled and felt within minutes; gummies are eaten, take longer to start and last longer. Green Vault sells all three, plus pre-rolls and THC drinks, to adult members across Johannesburg and South Africa from our store. This guide sets out which one suits you.
What is the difference between THC vapes, flower and gummies?
The biggest difference is the route: flower and vapes are inhaled, so you feel them within minutes, while gummies are eaten and absorbed through your digestive system, so they often take 30 minutes to 2 hours to start and last longer. The table compares them in general terms.
| Flower | THC vapes | Gummies | |
|---|---|---|---|
| How you use it | Grind and roll, or use a pipe or dry-herb vaporiser | Draw on a disposable pen | Eat |
| When you usually start to feel it | Within minutes | Within minutes | Often 30 minutes to 2 hours |
| How long it usually lasts | A couple of hours | A couple of hours | Longer, often several hours |
| Smell | Strong while smoking, lingers | Light, fades quickly | None |
| Discretion | Lowest | High | Highest |
| How it is dosed | By how much you roll and smoke | One puff at a time | A set strength per gummy |
| Kit you need | Papers or a pipe, a grinder helps | Nothing, ready to use | Nothing |
| Shop | Flower | THC vapes | Gummies |
Everyone responds differently, so treat the timings as a general guide, not a promise. The amount you take and the strength of the product matter as much as the format.
When does flower make the most sense?
Flower makes the most sense if you want the widest choice of strains and like being in control of how much you roll. It is the traditional way to use weed, and you can see, smell and handle what you have bought.
Green Vault's flower is sold by the gram and is craft grown: highest-grade organically grown cannabis from our own farm, sent farm direct with no middleman. Each product page shows whether the strain is listed as indica, sativa or hybrid and its THC from our product data. Recent strains include LA Cheese, Runtz Muffins, King Kush Breath, Tangie Bomb, White Snow and Strawberry Truffles.
The trade-offs are smell and effort. Smoke has a strong smell that stays in a room and on clothes, and you need papers or a pipe. If you like flower but not rolling, pre-rolls are king size 1.2g joints made from the same craft-grown flower.

Who are THC vapes best for?
THC vapes are best for people who want something discreet, quick and easy to keep small. A disposable pen is ready to use out of the box, and you can take one puff, wait, and decide whether you want another.
Vapes produce vapour rather than smoke, so the smell is lighter and fades faster. They fit in a pocket and need no papers, lighter or grinder. We stock two kinds:
- Disposable vape pens in strain-named flavours such as Blue Dream, Jack Herer, Cookie Dough and Northern Lights.
- Bhang Bar 2g Liquid Diamond disposables in flavours including Durban Poison Berry, Strawberry Cough Sundae, Grape Ape, Banana OG and London Pound Cake.
The downside is that you have less choice of strains than with flower, and a pen eventually runs out. Buy vapes only from a seller that shows you the product details before you pay, so you know what you are getting.

Are THC gummies a good choice?
Gummies are a good choice if you do not want to smoke or vape, want no smell at all, or like knowing the strength of each piece. Each gummy has a set strength shown on the product page, which makes it easier to repeat an amount you were happy with.
The catch is timing. Because gummies are eaten, they take longer to start and can feel stronger and last longer than the same amount inhaled. The most common mistake is taking more because nothing seems to be happening yet. The safer habit:
- Start with a small piece or a lower-strength gummy.
- Wait up to 2 hours before deciding whether to have more.
- Be at home with nothing you need to do later.
- Do not mix with alcohol.
Our Peach THC gummies come in several strengths, so there is a lower one to start with. You can find them in the gummies collection and on our edibles page.

Which is strongest: a vape, flower or a gummy?
No format is automatically the strongest. How strong something feels depends on the product's THC, how much you take and your own tolerance, not only on whether you smoke, vape or eat it.
That said, many people find an edible feels stronger and lasts longer than they expected, mostly because it is easy to take too much while waiting for it to start. With flower and vapes you feel the effect within minutes, so it is easier to stop when you have had enough. Check the THC shown on each product page and compare like with like.
Which should a beginner choose?
Most beginners find a disposable THC vape or a lower-strength gummy the easiest place to start. A vape lets you take one small puff and wait 10 to 15 minutes; a gummy gives you a measured amount, as long as you wait up to 2 hours before having more.
If you would rather start with flower, choose a lower-strength strain and take only a little. Our sativa vs indica vs hybrid guide explains the strain types, and our guide to the types of weed covers every format we sell.
Which is the most discreet?
Gummies are the most discreet because there is no smoke and no smell. Vapes come next, with a light smell that fades quickly. Flower is the least discreet, because smoke lingers.
THC drinks are as discreet as gummies. We stock Soda Fuze THC sodas, Zativa THC drinks and a Zativa Mojito 0% alcohol mocktail in the THC drinks collection. Like gummies, they take a while to feel, so sip slowly.
Whatever you choose, it arrives in sealed, plain, unbranded packaging, so nobody can tell what is inside the parcel.
