What Does 420 Mean?

Think of it as the Bat-Signal for cannabis culture. It started when some California high school students in the '70s, who dubbed themselves the Waldos, would meet at 4:20 p.m. every day to smoke. The term leaked out, hitched a ride with Grateful Dead fans, and blew up worldwide.

Now, April 20th is like New Year's Eve for cannabis consumers.

Legal Considerations When Attending 420 Events

Before heading to a 420 event, keep these legal factors in mind: 

• Age Restrictions: Most events require attendees to be 21+, though some allow 18+ entry for medical patients. Bring your card if you’re a patient.
• Public Consumption Laws: Even in legal states, smoking in public may be restricted. Stick to private venues or designated areas. 
• Prohibited Items: These include outside cannabis (if vendors are present), alcohol, weapons, and glass containers. Assume security will check your bags.
• Purchasing Limits: If cannabis is sold on-site, there may be purchase limits per person.
• Payment Methods: Cash is king. Most events are cash-only due to federal banking laws. ATMs on-site often charge hefty fees, so plan ahead.
• Traveling with Cannabis: Crossing state lines with cannabis is illegal under federal law.

For more details, review your state’s cannabis laws and regulations.

Tips for an Enjoyable Experience

To make the most of your 420 festival, follow these tips:

• Bring Essentials: Water, snacks, sunscreen, comfy shoes, portable charger, and cash (some vendors may not accept cards). Pre-game smart by locating a nearby dispensary before you go. Just be sure not to bring cannabis to events where it's not welcome.
• Know Your Limits: Start low and go slow, especially with edibles. Wait at least 2 hours before re-dosing.
• Plan Transportation: Designate a sober driver or use rideshare services (Uber, Lyft, etc.).
• Designate a Meet-Up Spot: Cell service often fails in dense crowds. Pick a visible landmark when you arrive.
• Respect Local Laws: Avoid public smoking if it’s prohibited. Only light up in designated areas.
• Connect with Others: The best connections happen in merch lines and food truck queues.
