seeing as u still dont understand that it is impossible to determine the weight of a substance via a photo, on the internet; as there are very great density differences between different buds...ill go ahead and just tell u again that u need to buy a scale and solve all of your problems.
regarding the lemon/lime flavor, it could have been sprayed with something to wet it down.
and btw, drug dealers don't calibrate their scales wrong. ones that do that dont know enough to be dealing drugs in the first place, or they're not going to be drug dealers very long (deaded). i called out my dealer on a 1.0g short bag yesterday, his response? sorry and ill make it up to you next time. he then proceeded to call me back and want to bring over the 1g, chill and blaze me out to make up for it. he knws im checking my bags now b/c the last one looked short (and i didn't have my scale at my gf's house to make sure, so i made sure to bring it this time), and now he wont pull the shit again b/c he knows ill call him out.
drug dealers know if they're fucking u or not. they know how much is in a 1/4oz, 1/

z, dime bag; whatever. its your job to either stop buying from them if u think they are, or man up and tell them to cut the shit out if they want to sell again. and honestly, without a scale; u have no way of telling if he is or not and calling someone out when they're not isn't smart either if u want to keep a hookup. looks like he was in this case, but again..just like you're here asking again, this bag could still be .2 short and you think you're getting 1g now and happy. and it will continue like this until u realize you're still getting shorted b/c u didn't want to spend that $15 on a scale. i guarantee it would have already paid for itself 3x by now u just dont really know.
when money and profit is involved, there is only one thing u can believe 100% of the time; and that is the other person is looking out for theirs. u better learn how to look out for yours unless u want to get taken advantage of.
