Understanding Cannabis Measurements

The Basics of Cannabis Weight Conversions

Cannabis is commonly measured in grams, ounces, and pounds. Understanding these conversions helps both casual users and bulk buyers.

• A quarter pound (QP) = 113.4 grams

Ounces to Pounds Conversion

• 1 ounce (oz) = 28.35 grams
• 4 ounces (oz) = 1 QP = 113.4 grams
• 16 ounces = 1 pound (LB) = 453.6 grams

What Does ‘QP’ Mean in Cannabis Terminology?

A QP (Quarter Pound) is a standard weight in the cannabis industry. It’s commonly used by:

• Dispensaries for bulk sales
• Medical patients who require large amounts
• Recreational users looking for better deals

Since 1 ounce is often the legal limit for possession in many places, buying a quarter pound of weed (QP) may not be suitable for personal use in regulated areas.

Practical Implications of a Quarter Pound

Visualizing a Quarter Pound of Weed

A QP of weed is equivalent to:

• 4 full sandwich bags (if loosely packed)
• Roughly 200–400 joints, depending on size
• About 20–30 blunts, depending on rolling style

Usage Scenarios

For Personal Use

• A quarter pound can last a moderate smoker several months.
• A heavy smoker might use a QP in 1–2 months.

For Medical Patients

Medical cannabis users often require higher doses, making buying in bulk (QP or more) a cost-effective choice.

For Dispensaries & Suppliers

Cannabis businesses often buy in QP or larger amounts to ensure steady supply and competitive pricing.

Legal Considerations of Possessing a Quarter Pound of Weed

Possession Limits

The legal limit for cannabis possession varies by state/country. In most legal markets:

Always check local cannabis laws before purchasing large amounts.

Penalties for Exceeding Legal Limits
