Why THC Strains Matter

If you’re looking for strong effects, high-THC strains are best. Cannabis or marijuana is a drug that is made from the flower of the cannabis plant, and it contains the main psychoactive compound THC — tetrahydrocannabinol — which is responsible for the euphoric and relaxing effects users feel when they consume it. Because strains with higher THC content produce more intense and longer-lasting effects, these high THC strains are recommended for people with more experience, or for people who are seeking relief for chronic pain, insomnia, or anxiety.

All medical marijuana evaluations and recommendations through CertaMD are performed exclusively by licensed U.S. healthcare providers using secure telemedicine technology, in accordance with applicable state laws and regulations.

Individual results and treatment response

Medical cannabis does not work the same way for every patient. Symptom relief can depend on factors such as the type of product (THC/CBD ratio, route of administration), dose, frequency of use, underlying medical conditions, concurrent medications, and lifestyle variables like diet, stress, and sleep.

Because response and tolerability vary, ongoing follow-up with your CertaMD provider is important to review benefits, monitor side effects, and adjust your treatment plan safely over time.

Possible risks and side effects

Like any therapeutic option, medical marijuana can cause side effects. Commonly reported effects include dry mouth, dizziness, fatigue, red or irritated eyes, increased appetite, headache, and temporary problems with attention, concentration, or short-term memory.

Some patients, especially with higher-THC products, may experience anxiety, rapid heartbeat, worsened mood, or perceptual changes; in rare cases, serious effects such as psychosis, significant mood changes, heart rhythm disturbances, or cannabinoid hyperemesis syndrome (recurrent nausea and vomiting) have been reported. If you notice severe, unexpected, or persistent symptoms, stop using cannabis and contact your healthcare provider or seek urgent care.

Legal and regulatory notice

Medical marijuana programs are created and regulated at the state level, and eligibility, product access, and telemedicine rules vary by jurisdiction. Under U.S. federal law, marijuana remains a Schedule I controlled substance, and clinicians typically “recommend” or “certify” medical cannabis use rather than prescribe it in the traditional sense.

Some states require an initial in-person visit before medical cannabis certification, while others allow both initial and renewal evaluations via telehealth; CertaMD operates within the specific requirements of each state it serves.

Product quality, sourcing, and safety

For your safety, use only medical cannabis products obtained from licensed, state-regulated dispensaries that perform appropriate laboratory testing for potency and contaminants. Unregulated or illicit products may contain pesticides, heavy metals, microbes, or inaccurate THC/CBD concentrations, which can increase health risks and lead to unpredictable effects.

Ask your CertaMD clinician or dispensary pharmacist about product selection, dosing, onset and duration of effects, and how to store products safely away from children and pets.

Reporting adverse events and safety concerns

If you experience serious or unexpected side effects while using medical cannabis, contact your healthcare provider immediately or seek emergency care when appropriate.

Patients and caregivers in the United States can also report adverse events and product problems to the FDA’s MedWatch program online or by phone at
1-800-FDA-1088, which helps regulators monitor safety trends and protect public health.
