How can I choose PDI as my designated Illinois medical cannabis dispensary?

PDI Medical is on the Illinois list of registered cannabis dispensaries.

If you have already chosen another dispensary, you can fill out and submit a new Illinois dispensary selection form. If you need help, we can walk you through the process. Feel free to contact us for assistance or stop by.

What forms of payment to you accept?

At the present time, we can only accept cash.  We also have two ATM machines on premises if needed.

What is the return policy?

The State of Illinois does not allow dispensaries to accept Cannabis products back as returns. According to IL Law, patients Can Not bring Cannabis products back into the dispensary for any reason. We realized that occasionally you may encounter a defective product and we will work with you to remedy the situation. Please go here for step by step instructions:

Why should I choose PDI?

  • We are medical professionals. Pharmacists are the most trusted professionals in the US. Our pharmacist owners and product specialists help each patient develop a holistic, integrative medical treatment plan based on your unique history and profile.
  • One-stop shop. Obtaining and using medical marijuana can be frustrating for sick patients. PDI’s staff and state-approved services (fingerprinting, passport photos) can help you get your patient and/or caregiver cards.  Our staff will help select the right cannabis-based medicine, and choose the most effective route of administration.
  • We care about you. We provide medical cannabis to patients who need relief. Cannabis is medicine.  It should be dispensed carefully. We listen to and work closely with our patients and their caregivers to solve challenges and find the solutions that will improve their quality of life.
  • Locally owned and operated. Many dispensaries are corporately owned, without local ties. At PDI, we have lived and worked in this community for decades. Our children go to school here. We work hand in hand with the Buffalo Grove Chief of Police, Fire Chief and Community Development Director.

Who can apply for a medical marijuana card in Illinois?

Every state has different rules from the amounts of medical cannabis a patient can have to who can grow it and where and what diseases or conditions qualify.

Caregivers and patients can apply. See our current list of Illinois approved health issues and conditions that may qualify for you for treatment with medical cannabis.

Do I have to buy cannabis at the dispensary nearest to me?

No, you are free to buy medical cannabis at the dispensary that best fits your needs. However, patients must purchase from the dispensary they are registered to.  Changing dispensaries is an easy process.  There is no cost involved.  The PDI Medical staff can help.  Just call us at 224-377-9PDI (9734)

Is there a short history about the Illinois Pilot Program?

​Yes. Right here. The chief sponsor of the Illinois Compassionate Use of Medical Cannabis Pilot Program was State Representative Lou Lang. His bill passed the Illinois General Assembly by one vote and was signed into law during the summer of 2013, making Illinois the 20th state to legalize medical marijuana. The law became effective on January 1, 2014. As required, state agencies held many public hearings and studied the rules and regulation — and results — from other jurisdictions.

They made the applications for cultivation centers and dispensaries available in August 2014. Completed applications for dispensaries were submitted between September 2 and September 22, 2014, and will be evaluated according to a rigorous point system. After 2.5 years, the state granted licenses to 54 dispensaries and 14 cultivation centers. You can access the law on the Illinois General Assembly’s website.

Is the Illinois Program permanent?

No. The program in Illinois is a pilot program. The current law is scheduled to be repealed July, 2020. If Illinois does this correctly, another law to extend the program or make it permanent may be passed so registered qualifying patients will be able to continue receiving the benefits they need.

Is there an age requirement for patients?

Not necessarily. Registered qualifying patients must be at least 18 years old. However, children and teenagers with the covered diseases and conditions may be granted permission to use medical cannabis products.  A primary physician plus a reviewing physician certification form are necessary for patients under the age of 18.  No forms of inhalation (vaporization or combustion) are allowed for patients under the age of 18.

Does medical marijuana always make you high?

Absolutely not. In fact, the “high-making” cannabinoids are often purposely produced in negligible or sub-therapeutic amounts in cannabis-based medicinal products during the processing stage. This is particularly important for children and teens with special health needs.  However, THC does in fact have therapeutic value.  The PDI Medical staff will work carefully with each patient to help determine the best dosing algorithm of the THC and CBD components of medical cannabis.

Isn’t marijuana illegal?

It’s a complex situation. At a state level, as of July 2018, a total of 30 states, the District of Columbia and Guam now allow for comprehensive public medical cannabis programs.  There are 8 states that now allow for adult-use cannabis.

Although cannabis is still illegal federally, the US Department of Justice had stated it would no longer enforce its laws against cannabis where cannabis has been declared legal for medical and/or recreational use. In other words, the federal government has said that it won’t shut down state cannabis programs.  However, Jeff Sessions, U.S. Attorney General rescinded these protections on January 2, 2018 which may affect adult-use programs.  Medical cannabis programs are still protected under separate federal legislation.  See Dr. Sanjay Gupta’s CNN essays on August 2013 and March 2014, and PDI Medical’s Joseph Friedman’s article in Drug Topics.

When did marijuana become illegal in the United States?

Using cannabis became illegal in the United States in the 1930s and became a Schedule I drug in 1970. See Dr. Sanjay Gupta’s CNN essays on August 2013 and March 2014 and PDI Medical’s Joseph Friedman’s article in Drug Topics.

Do you have to smoke medical cannabis?

Not at all. Smoking is only one way to administer medical cannabis. Other methods include vaporizing, topical applications (oils, ointments, balms, & patches), tinctures & sprays under the tongue, tablets, capsules, suppositories, and edibles.

Where is medical cannabis legal in the United States?

As July 2018, 30 states, Washington DC and Guam, 32 jurisdictions in all, have legalized the use of medical cannabis. States include Alaska, Arizona, California, Colorado, Connecticut, Delaware, District of Columbia, Florida, Hawaii, Illinois, Maine, Louisiana, Maryland, Massachusetts, Michigan, Minnesota, Montana, Nevada, Ohio, New Hampshire, New Jersey, New Mexico, New York, Oregon, Pennsylvania Rhode Island, Vermont, Washington.

What’s a Schedule I drug according to the Controlled Substances Act of 1970?

A Schedule I drug has a high potential for abuse, has no accepted medical use, and cannot be used safely. Individual states, such as Connecticut and Oregon, have reclassified cannabis as a Schedule II drug.

Will health insurance pay for medical cannabis?

Not as far as we know. As long as cannabis remains a Schedule I drug, it’s unlikely to be covered by health insurance.  However, we absolutely expect this Federal Schedule 1 status to change.  When that happens, health insurance may begin to cover cannabis-based medicine.  PDI Medical will be one of the first dispensaries in the nation to adjudicate health insurance claims.  PDI Medical is going through an accreditation process.  Health Insurance companies will seek out accredited dispensaries only for this service.  Our PDI Medical Pharmacists are very familiar processing insurance claims for drug coverage.
