Why Does It Even Matter?
Gaining the mental and physical benefits of cannabis is largely dependent upon how it’s consumed, with each method providing a unique experience and host of effects. There are three basic delivery methods: inhalation, oral, and topical. Under these umbrella methods are various techniques that serve unique functions, each appropriate for treating different conditions.
When cannabis is inhaled, the gases enter the lungs before absorbing into the bloodstream. There are currently two prevalent types of inhalation methods: smoking and vaporization.
This ancient custom is the method most commonly associated with cannabis. However, advances in vaporization technology have offered smokers an alternative method with fewer health concerns. The effects associated with smoking are widely debated, but health professionals are in agreement that smoke-free methods pose less risk and are medically preferred.
Cannabis smokers have a wide array of devices at their disposal, including hand pipes, water pipes, rolling papers, and hookahs. Each of these provides different experiences and influence the grade of smoke inhaled.
Vaporizers are the logical choice for moderate to experienced and/or health-conscious cannabis consumers. A vaporizer steadily heats herbs to a temperature that is high enough to extract THC, CBD, and other cannabinoids but too low for the potentially harmful toxins that are released during combustion; essentially, vaporization eliminates the health risks associated with smoking. This improvement comes with an equally significant reduction in odor, which is generally the first acknowledgement of first-time vaporizer users. There is a diverse landscape of vaporizer models and the market is only expanding as the technology improves.
There are multiple elements that distinguish vaporizer designs, markedly portability and product. As the market grows, so does the efficiency and quality of portable models, which generally fall short to fixed models (requiring an outlet power source) in durability and robustness. The form of cannabis product is the other primary component: many vaporizers take cannabis concentrates which come in a variety of forms including oil and wax. These can be added manually or using cartridges, depending on the design. The prevalence of concentrate vapes is due to mechanical simplicity; fewer vaporizers take flower, which require a heating element to accomplish vaporization, and thus a more sophisticated design.
A younger delivery method that is a point of contention amongst the cannabis community and attentive policy makers is dabbing. Dabbing is a form of vaporization in which potent cannabis concentrates are dropped on a heated nail, creating vapor that is trapped in a glass globe and inhaled. Although there are obvious health benefits associated with clean concentrates over combustible flower, concerns arise from dabbing’s image and the intense effects of high-THC extracts.
Oral Delivery Methods
Oral delivery includes all techniques that are administered through the mouth, including tinctures, ingestible oils, and infused food/drinks. We most often assume that oral delivery denotes ingestion through the digestive tract before entering the bloodstream, but this is not always the case. Tinctures are essentially a topical application that is administered through the mouth, and they are immediately absorbed into the bloodstream unlike edibles or drinks.
Tinctures are a liquid cannabis extract used by consumers looking for dosage control and fast-acting effects without the health risks associated with smoking. Most commonly, alcohol is used as the solvent (any proof greater than 80 can be used effectively), but other fat-soluble liquids can be used as well, such as vinegar or glycerol. Generally, three or four drops of the tincture are placed under the tongue, where it’s absorbed into the body versus swallowed and digested. When ingested, tinctures are immediately absorbed in an empty stomach but require time to process through the liver, reducing dosage control.
Ingestible oils are a happy medium between edibles and concentrates: they are swallowed and digested like an infused product, but often have the consistency of oil. These oils can either be eaten or put in easily-ingested capsules. One popular oil is Rick Simpson Oil (RSO), which originated in 2003 when Simpson used hemp to treat his skin cancer. RSO is made by extracting the therapeutic compounds of cannabis with alcohol and then evaporating the solvent, leaving behind a tar-like substance resembling oil.
Eating or drinking cannabis provides significantly different effects from delivery methods that immediately enter the bloodstream, such as smoking or vaping. Edibles can be defined as any food that contains cannabis, whether or not the cannabinoids are bioavailable. These products have longer onsets and tend to cause powerful full-body, psychoactive effects.
Infused food and drinks can be made a variety of ways depending on the dish. Most often, edibles are infused with a staple infused ingredient high in fat — like butter or olive oil — that enable extraction of the plant’s therapeutic properties. Adding tinctures to dishes is another great option for dosage control and simplicity. Generally, cooking with cannabis flower can be difficult because of the complication associated with cannabinoid activation (including sensitive heating temperatures and times, and sufficient solvent fat). However, as the prevalence of cannabis grows, so does the presence of flower in the kitchen.
Topical Delivery Methods
Topical cannabis administration utilizes full cannabis extract — a thick oil that has been decarboxylated to activate cannabinoids. Once cannabinoids are activated, they can be absorbed through your skin.
Topical effects differ from other medicating methods in that they don’t provide the cerebral stimulation that users describe as “being high.” Because of this, topicals are appropriate for consumers needing a clear head and localized relief (for example, muscle aches or soreness).
