Fentanyl pills and powder are becoming more available across the country in a variety of colors, shapes and sizes. Rainbow fentanyl, named for its bright colors, is highly addictive and potentially deadly. It is specifically marketed to appeal to children and young people and looks like candy or blocks similar to sidewalk chalk. Every color, shape and size of rainbow fentanyl is illegal and extremely dangerous. Remember: while fentanyl can be safely prescribed for severe pain and obtained from a pharmacy, it can also be made and distributed illegally (like rainbow fentanyl) or found mixed in other illegal drugs. Know the difference and what to look out for when using prescribed fentanyl to keep your health and career safe.
