Report a Medical Cannabis Adverse Reaction
Experiencing an unexpected or uncomfortable reaction to your medical cannabis product? Reporting helps us investigate product issues, coordinate with dispensaries and manufacturers, and protect the broader Pennsylvania patient community.
Your report makes a difference
Even mild reactions can signal product-level issues. Reporting helps us investigate, follow up, and protect every patient in the Pennsylvania medical marijuana program.
Identify Product Issues
Your report helps determine whether a reaction is isolated or part of a broader batch or product-level concern that may affect other patients.
Enable Accountability
We can contact the dispensary or grower-processor on your behalf, request investigation, and escalate to the PA Department of Health when warranted.
Protect Other Patients
Aggregate reports help identify patterns and improve safety standards across the Pennsylvania medical marijuana program for every patient.
Your health is our priority. Thank you for taking a moment to report what happened. Every report is reviewed, and your information helps keep this program safer for everyone.

Common questions about reporting
Quick answers to what Pennsylvania medical cannabis patients ask most often before submitting a report.
What counts as an adverse reaction to medical cannabis?
Any unexpected or uncomfortable physical or psychological response to a medical cannabis product — mild or severe. Common reports include dizziness, severe anxiety, persistent nausea, headaches, unusual taste or odor, and product quality issues. More serious reactions can include chest pain, difficulty breathing, swelling, persistent vomiting, or loss of consciousness.
When in doubt, report it. Even mild reactions can signal a product-level issue that affects other patients.
Do I have to be a Green Bridge Society patient to report a reaction?
No. Any Pennsylvania medical cannabis patient can submit a report. You don't need to have been certified through Green Bridge.
How long does it take to hear back?
Most reports are reviewed the same business day or the next. You'll typically hear from us within 1–2 business days. Severe or urgent reports are prioritized.
Will my name be shared with the dispensary or manufacturer?
Only with your consent. When we follow up with a dispensary or grower-processor, we ask permission first and can keep your identity confidential to the extent possible. If you prefer anonymous handling, note that in your email.
What if I don't have the batch number or product label?
Send what you have. A product name, brand, and dispensary location is enough to start. We may follow up with questions, and we can often look up batch information through the dispensary if needed.
Is this report the same as reporting to the PA Department of Health?
No, but they can be connected. Green Bridge handles the investigation and dispensary coordination. With your permission, we can escalate to the PA Department of Health when warranted. You can also report directly to the Department of Health if you prefer.
Should I stop using the product before reporting?
If you suspect a product caused a reaction, stop using it and set it aside in its original packaging — don't throw it away. The packaging and remaining product help us investigate. If symptoms are severe, seek medical care first, then report.
