Tincture of cannabis

Tincture of cannabis is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Tincture of cannabis rather than just read about it. In short: Tincture of cannabis, sometimes known as green dragon, is an alcoholic cannabis concentrate. The solubility of THC in ethanol is greater than 1 g/mL.

Key takeaways

Tincture of cannabis belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Tincture of cannabis to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Tincture of cannabis from memory before moving on to harder problems.

Reference excerpt

Tincture of cannabis, sometimes known as green dragon, is an alcoholic cannabis concentrate. The solubility of THC in ethanol is greater than 1 g/mL. According to the European Medicines Agency (EMA) cannabis tinctures (tincturea) are a type of liquid cannabis extract obtained using ethanol, water, glycerol, propylene glycol and fatty oils as extraction solvents, depending on the type of tincture (and also on the solvent used) it can have a specific mass/volume ratio or a specific therapeutic agents content. Cannabis tinctures are used in the production of specific extracts, like nabiximols.

History

Cannabis tincture appeared in the United States Pharmacopoeia until 1942 (Australia 1977, UK 1970s). The pharmacological target for cannabis, the endocannabinoid system, has been researched since its discovery in the 1980s.

Preparation The tincture is typically made by soaking the dried flowers of the female hemp plant (marijuana) in ethanol. The tetrahydrocannabinol (THC) and other cannabinoids dissolve into the alcohol. Some preparations also extract some of the water-based plant products such as chlorophyll, resulting in a dark green or brown liquid. Baking or drying the cannabis to decarboxylate prior to the alcohol bath increases the amount of THC in the resulting preparation.

Methods of use The tincture is ordinarily consumed orally, but may also be applied to the skin.

Worked examples

Example 1 — a first encounter with Tincture of cannabis

Start with the simplest possible case. Write down what Tincture of cannabis claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tincture of cannabis before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tincture of cannabis ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tincture of cannabis

In research: Tincture of cannabis appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Tincture of cannabis in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Tincture of cannabis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cannabis culture, Cannabis foods, Mixed drinks, so understanding it makes those chapters shorter.
In everyday life: Look for Tincture of cannabis outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
