The US marijuana market is estimated at $50 billion — substantially smaller than the tobacco industry, but less likely to kill its users with cancer. And with the way legislation is heading, the market should grow at a healthy pace.

Weed users are an underserved market segment and there are many opportunities waiting to be exploited. A new cannabis-focused private equity fund is now receiving investor pitches.

Here are some business ideas that I hope someone invests in.

• Weed chia pets so you can get your kids to grow weed for you
• Genetically modified crops
• Piracetam as a supplement to counteract marijuana-induced mental retardation
• Delivery service for Cheetos, m&m’s, and gummy bears
• Arboretum set up to look like Alice in Wonderland
