Looking for information on which states allow out-of-state patients to buy medical marijuana? Look no further! This comprehensive guide provides everything you need to know on the subject.

If you’re planning to travel out of state, you may wonder if your medical card is valid in another state. Medical marijuana laws vary significantly from state to state. These laws usually include using low-THC products and removing criminal penalties for Medical cannabis patient cardholders. 

Certain states allow out-of-state patients to purchase and possess specific amounts of cannabis; however, it varies significantly by location and their established medical marijuana program. Read on to find out more about out-of-state reciprocity in your location. 

What is Medical Marijuana?

Medical cannabis is available nationwide in over thirty states and for many patients with qualifying conditions within those states. 

Patients can use medical marijuana to treat various conditions, ranging from chronic pain, neurological disorders, Crohn’s disease, epilepsy, and insomnia to cancer, PTSD, anxiety, depression, chronic stress, Multiple Sclerosis, or HIV/AIDS. Medical marijuana is still federally illegal but has been decriminalized or legalized in many areas.

In the United States, medical marijuana programs have been legalized in 37 states: the District of Columbia, Puerto Rico, Guam, and the U.S. Virgin Islands. Medical marijuana programs allow patients with specified conditions to own, grow and utilize cannabis products to aid in managing their condition, even if recreational cannabis users are not authorized.

Health Benefits

The potential benefits of medical treatment with cannabis are vast. Specific cannabinoids can produce a therapeutic potential for patients with different health conditions.

Several peer-reviewed studies suggest that cannabinoids have varying health benefits. They have been used throughout history to manage various health concerns and ailments. While research continues, more evidence suggests that cannabis and cannabinoids can benefit human health.  

Studies are being done worldwide to see how cannabis may aid in fighting cancer, slowing down tumor growth, and if cannabinol delays symptom onset for certain chronic pain conditions. It can help with addiction treatment, increase appetite, aid in sleep, improve muscle function, and manage seizures, and it has significant anti-inflammatory benefits. 

Marijuana has many potential medical uses, including:

  • It effectively reduces pain, nausea, and vomiting associated with cancer and other illnesses. 
  • It may also be used to manage mental illnesses such as PTSD, schizophrenia, and bipolar disorder. 
  • Marijuana has also been shown to reduce intraocular pressure in the eyes of people with glaucoma. It may cause the pupil to constrict, reducing the pressure inside the eye.
  • Seizure management, particularly from epilepsy. 
  • Diseases such as Crohn’s disease, HIV/Aids, Multiple sclerosis, and Alzheimer’s. 

Potential Risks

There aren’t many known side effects for CBD, and most side effects from marijuana come from higher doses and long-term use. 

Marijuana also affects brain development if used at an early age. When people begin using it as teenagers, it can impair cognitive functions and affect how the brain connects and communicates with other body areas. 

Other adverse side effects include:

  • altered senses or sense of time
  • mood changes
  • impaired body function
  • slowed memory and thinking skills
  • hallucinations or delusions (high doses only)
  • psychosis (high doses, significant long-term use only)
