Usually I will put in 0.5g if its for myself...

Or if Im with my friends and want to get really mashed I'll put a 1g+ in each joint.

If Im rolling a blunt I'll use a whole teenth.

You may say WTF! to how much I put in my blunts, but in England your lucky to find a decent sized cigar for under £5, I rather spend the money on weed and get more kaned!
