Depending on the dosage, the majority of users start to experience the effects of CBD within 15 minutes. How long the effects last is dependent upon the method of consumption. What you need to remember is the effects of sublingual placement or consumption last longer than vaping or smoking. It is also safer to consume CBD sublingually or through ingestion. 

An appetite stimulant, a sleep aid, and one of the safest treatments for skin problems. But the question is, how safe is CBD, and how does it affect your overall health?

Quick take: Is CBD safe?

• According to the FDA, CBD is safe and no addictive. 
• CBD side effects wear off once the user ceases consumption.
• CBD side effects are mild and there is zero risk of overdosing. 

What are the positive side effects of consuming CBD products?

CBD is a product of cannabis or hemp. To the FDA, any product that contains more than 0.3% THC is considered marijuana. Outside of Canada, marijuana remains a schedule 1 substance, meaning selling it or using it may get you in trouble with the law.

CBD, on the other hand, is legal in the majority of states, and it is lawful to travel with across state lines. Also, hemp derived CBD is legal across all states. 

That said. 

The positive side effects of using CBD, according to medical research and anecdotal evidence, include:

• Acne. CBD has a positive effect on acne, and can help relieve and prevent it. There are no laws that prohibit the topical application of CBD products. 
• Psychosis, ADHD, PTSD, and other mental conditions. CBD supports neurogenesis, and it has neuroprotective properties. This makes it useful in the treatment of diseases and disorders that affect the brain, including epilepsy. The FDA has approved epidiolex, a synthetic form of CBD, as a treatment for epileptic seizures.
• Cancer. CBD is not a cure for cancer, but it can help in pain management, and offers some benefits for patients on chemo. 
• Chronic pain. 
• Depression, anxiety, and stress. CBD’s anxiolytic properties can help users prevent or treat anxiety. 
• Glaucoma.  
• Healthy skin. CBD can treat skin conditions, including psoriasis and eczema.
• Hypertension/high blood pressure.
• Poor appetite. CBD is a mild appetite suppressant that can help you lose weight. 

Clinical and anecdotal evidence says that CBD may be useful in the treatment of over 50 conditions, including the ones listed above. 

Till recently, cannabis and all its products were legally considered schedule 1 substances in the US, meaning research into the potential benefits of CBD is still in its infancy. However, users report positive effects.

Cannabidiol: What all users should know and is Hemp CBD the same as CBD?

Hemp is a variety of cannabis/marijuana that contain little to no THC. Without THC, the user will not experience a high effect. Hemp CBD differs from hemp oil -in that- the latter is extracted from the seeds only. The benefits of hemp oil and CBD are not the same. But the commonality is both products can help relieve pain and inflammation. 

How does CBD affect the eyes?

According to the FDA, CBD can increase pressure on the eye, meaning it may be unsuitable for persons who have glaucoma. THC or marijuana, on the other hand, has been shown to lower pressure in the eyes.

The studies on CBD’s effect on the eyes conflict, meaning more research is needed. 

What we do know is in low doses, CBD possess little risk of adverse side effects, and the positive side effects outweigh the negative. 

We, therefore, recommend consulting with a physician before treating any eye condition you may have with CBD. 

CBD’s effect on the eye, what we know:

• THC can help relieve pressure in the eyes.
• At high doses, CBD may increase pressure in the eyes.
• Full spectrum CBD products may contain THC. 
• CBD is not a cure for glaucoma, but THC could be (more research is necessary).

Is CBD good for the eyes? 

Current research says no. But THC has a positive impact. So, we recommend full spectrum CBD if you have glaucoma.

Is CBD good for eye inflammation?

Clinical trials say yes, CBD can relieve inflammation anywhere on the human body. But smoking may lead to eye dryness or other issues.

Does CBD cause tingling?

Tingling can be a sign of anxiety, infection, or pressure. It can also be a sign that the product you are consuming has contaminants.  Signs that tingling is related to anxiety or panic include dizziness, numbness in the limbs and face, and tingling.

Some experience numbness. 

Often, these sensations will go away if you relax your mind and body. But it is advisable to:

• Only purchase CBD products from trustable sources.
• Test the product. Contaminants including THC can trigger panic attacks and tingles. 

When to see a doctor

If tingling is accompanied by numbness, an inability to move your limbs, or an inability to speak. You should see a doctor immediately. 

Is it low blood pressure?

Low blood pressure or hypotension is the opposite of hypertension. If your blood pressure is low, one of the signs is tingling. Medical experts advise against using CBD if you have hypotension because the chemical can lower blood pressure. 

What we know:

• CBD lowers blood pressure, meaning some users may experience tingling and lightheadedness after use.
• If you experience negative side effects of CBD, relax, and wait it out. The effects will diminish once the chemical is out of your system.
• Keep the dosage low to avoid adverse side effects if you are at risk. 

Is CBD addictive?

Human and animal trials say that CBD is not addictive and holds the promise of treating use disorders related to cocaine, psychostimulants, opioids, and opioid-based painkillers. 

The reason CBD may not trigger addiction is in the way the chemical interacts with the brain. 

What happens when you take cocaine, opioids, or other stimulant is that the chemicals “hijack” your brain’s function in some way. Depending on the drug, it could trigger a pleasure response, hunger/suppression, or other effects. 

According to one study, CBD can quote:

“Growing evidence suggests that CBD could potentially be added to the standard opioid detoxification regimen to mitigate acute or protracted opioid withdrawal-related symptoms.”

CBD and addiction: what we know

• CBD may have benefits for persons struggling with substance abuse disorder.
• When combined with THC, CBD can decrease withdrawal symptoms triggered by opioid use. 
• CBD can help reduce drug-seeking behavior related to methamphetamine, heroin, and cocaine (based on animal studies).

What effects should I experience after consuming CBD?

According to human trials, within 15 minutes to an hour of consuming CBD. The user may experience:

• Deep relaxation. At high doses, cannabidiol has sedative properties, meaning it can put you to sleep.
• Awake and active. At low doses, CBD has stimulating effects, making it useful before working out or before work. Unlike THC, you will not experience a high effect.
• Pain relief. Patients who suffer from chronic pain report pain and inflammation relief.
• Minimal anxiety. By improving circulation and slowing down the overactive mind, CBD can induce stress relief. 

What about fatigue?

As mentioned, at high doses CBD may trigger sedation and fatigue. That is useful for persons suffering from insomnia or other sleep-related conditions.

If you take too much cannabidiol, fatigue may last for a few days, no longer than a week or two if you reduce or cease use.

What are the negative side effects of CBD?

The negative side effects vary depending on the consumer and dosage. Some can tolerate high doses, and some may suffer the side effects listed below. We, therefore, recommend that you start at small doses until you reach a level you are comfortable with.

• Dry mouth. You prevent or cure dry mouth by chewing sugar-free gum, limiting caffeine intake, or sipping a beverage of your choosing slowly. Dry mouth should last a couple of minutes or hours, nothing serious.
• Diarrhea. Carrier oils including coconut oil may cause an upset stomach and so can consuming too much CBD. If you experience stomach problems, you should lower or limit CBD intake. 
• Dizziness. Could be a sign of low blood pressure, sitting too long, medication, infection, injury, motion sickness, and so on. We recommend not mixing CBD with alcohol or medications that may trigger it. 

Avoid CBD if you have the following conditions:

• Are pregnant or nursing? The FDA says that CBD and contaminants, including THC may pass to the fetus or baby through breast milk (the long-term side effects are under investigation).
• Glaucoma patients. As mentioned, CBD may increase pressure in the eyes and may cause dry eyes.
• Low blood pressure.
