hi madam, welcome to health care magic, I can certainly understand your concern towards your marijauna smoking habbit, as the amount of time that weed stays in your system depends on how frequently you smoke, and your body metabolism. As long as you continue to consume cannabis, THC keeps getting accumulated in the body. The more you consume, the longer it will take to clear out. The hair sample will provide a record of your overall health and what you’ve consumed over the past three months, anyway it seems negative in your case you have consumed twice in one and half week during september, which is long back, it would have taken around 5- 8 days that time to get clear from the body, so nothing to worry currently, there will be nothing left now to have any effects, hope this information would help you. post your further questions if any, I will always be available to take up follow up questions thank you
