As lawmakers in Washington State continue to work out the details of how to regulate a recreational-pot market, hundreds of ā€œgreenā€ entrepreneurs are looking for ways to bank on the budding industry.

From cannabis-friendly bowling alleys to cannabis cruises, lawyer Hilary Bricken, who specializes in cannabis issues, said a number of Washington residents have approached her with creative ideas on how to capitalize on the potential influx of pot tourists.

Once the veil surrounding the stateā€™s hazy marijuana laws have been lifted, people hope to cash in.

ā€œWe call it cannabis tourism,ā€ Bricken told Ā鶹“«Ć½. ā€œIf the right entrepreneurs get involved and they invest, we could be the Amsterdam of the United States.ā€

But those pot ventures will have to wait ā€“ at least for now.

The people of Washington voted to legalize and tax the sale of marijuana to adults over 21 last November in a citizensā€™ ballot initiative ā€“ it passed by a margin of 56 to 44 per cent ā€“ but it remains illegal under federal law, through the Controlled Substances Act.

Smoking the drug in public is still forbidden under Washington law, punishable by a civil infraction carrying a $103 fine. The sale of marijuana without a doctor`s note is also banned.

Everything from who gets to grow pot to how it gets taxed has to be figured out.

ā€œIt is lots of work involved,ā€ Brian Smith, a spokesperson with the Liquor Control Board, said of writing new pot laws. ā€œWe are developing something that doesnā€™t have a blueprint.ā€

The U.S. Justice Department could also sue the state in an attempt to block licensing schemes from taking effect.

Last month, the Washington State Liquor Control Board gave the public a taste of what a legal pot state would look like after releasing a set of draft rules. The 46-page document covered an array of issues including labelling, product testing, advertising, and growing licenses.

The sale of marijuana is expected to begin in early 2014.

In Canada, pot-advocates such as Sensible B.C. have been watching the developments in the U.S. closely to see what ā€“ if any ā€“ new lessons can be applied north of the border.

The group will be launching a 90-day campaign in September to collect enough signatures from registered voters in B.C. in order to trigger a referendum in 2014 to decriminalize pot.
