I have. But it's illegal of course. In fact the penalties for growing tobacco are worse than for weed.

• Penalties for possessing more than 2 and less than 5 kilograms of illicit tobacco include a civil fine of $27,500
  
• Penalties for possessing 5 kilograms or more of illicit tobacco include a criminal penalty such as prison sentence of up to 5 years or a fine between $55,000 and $275,000, or both.
  
• Penalties for selling or buying illicit tobacco products include a criminal conviction with a prison sentence of up to 5 years or a fine between $55,000 and $275,000, or both.
  
• Penalties for manufacturing or producing illicit tobacco include a criminal conviction with a prison sentence of up to 10 years or a fine between $137,500 and $412,500, or both

This is why i'm wary of pot being legalized in Aus. Before you know it, it will be controlled by big corporations, taxes will go through the roof, & home-growers will face fines/jail time like the above.
